NEAR INFRARED SPECTRUM OF
No full textAuthor Institution: Department of Physics and Astronomy, Michigan State CollegeThe first (2-0) and second (3-0) overtones of DCl have been obtained with high dispersion in the 2.4 and 1.6 regions. The dispersing system consisted of a recording vacuum spectrograph equipped with a 15,000-line-per-inch grating and a lead sulfide detector. Calibration was obtained by making use of the second order Argon emission lines and Fabry-Perot etalon fringes. Analysis yields molecular constants essentially in agreement with those obtained by Pickworth and for the fundamental. In addition the data yields values for the anharmonic constants. These values agree within experimental error with the calculated values as based on the data for HCl
PROFILE OF THE ROTATION-VIBRATION FUNDAMENTAL OF HCl AND DCl IN SOLUTION
No full textAuthor Institution:The correlation-function approach to the analysis of absorption-band shapes has been used in studies of HCl and DCl in solution over a range of temperatures. The isotope effect on the band moments will be discussed in terms of the rotation-translation coupling model
THE INFRARED EMISSION SPECTRUM OF DCL
No full textAuthor Institution: Department of Chemistry, University of WaterlooThe vibrational rotational emission spectrum of DCl was recorded with a Fourier transform spectrometer; line positions for the 1-0, 2-1, 3-2 and 4-3 bands of and the 1-0, 2-1 and 3-2 bands of were measured. The two sets of data were combined with previously measured submillimeter were pure rotational transitions to obtain Dunham constants. A combined isotopomer analysis of data for all four isotopic forms of HCl was also performed combining these new data with analogous literature results for and , to yield Born-Oppenheimer breakdown correction terms for this system. The results of similar analyses of HF and HBr allowed a comparison of Born-Oppenheimer breakdown correction terms for HF, HCl and HBr

Nesbitt (in preparation)Author Institution: Joint Institute for Laboratory Astrophysics, University of Colorado, and National Institute of Standards and Technology, and the Department of Chemistry and Biochemistry, University of ColoradoRecent high resolution infrared spectra recorded on a difference frequency and Pb-salt diode laser spectrometers have been obtained for and complexes, respectively. Analyses of these systems are used to characterize the internal rotor motion of the and the intermolecular potential which orients the subunits into a T-shaped asymmetric top complex. The spectra provide an opportunity to study any preferential orientation of DCl systems versus their HCl analogs. Such a differential intermolecular orientation has been demonstrated both and for rare gas . H(D)Cl complexes. The vibrationally averaged geometries of and are of interest since these systems provide a means of investigating photo initiated chemical insertion reactions of and $H + D_{2}
ANALYSIS OF AUTOIONIZING RYDBERG STATES IN THE VACUUM ULTRAVIOLET ABSORPTION SPECTRUM OF HCl AND DCl
No full textAuthor Institution: Department of Chemistry, Yale UniversityThe photographic absorption spectra of HCl and DCl have been analyzed above the 1st ionization potential ( \AA). Rydberg series converging to the 2nd ionization limit () have been identified with quantum defects of 1.8 and 2.2. No rotational structure was observed in either series, indicating that the autoionization rate is faster than the rotational period (about for the lowest members of the two series). The symmetries of the Rydberg states cannot be determined conclusively since the rotational fine structure is obscured. Photoelectric studies of the absorption spectrum are underway in order to determine the relative intensities and lineshapes of the individual transitions
Determinants of cross-country income inequality : an augmented Kuznets hypothesis
No full textWhy does income inequality differ among countries? Using a sample of 80 countries from the 1980s, the author shows that two types of factors explain variations in income inequality. The first are factors that are, in the short term, independent of economic policies and are included in the standard formulation of the Kuznets'curve: the level of per capita income and the country's regional heterogeneity. From the viewpoint of economic policy, these are"given"factors, resulting in a"given inequality."The second group of factors are the social-choice factors reflected in the sizeof social transfers and of state sector employment, both of which reduce inequality. For this sample, the reduction amounts to about a quarter of"given"inequality. The importance of social-choice factors rises as the level of income rises. The divergence between actual inequality and the inequality predicted by the standard Kuznets'curve therefore systematically widens as a society develops. This discrepancy is systematic, the author contends. Inequality in richer societies decreases not only because of economic factors but also because societies choose less inequalities as they grow richer.Inequality,Poverty Impact Evaluation,Environmental Economics&Policies,Services&Transfers to Poor,Safety Nets and Transfers
HIGH RESOLUTION ABSORPTION SPECTRA ASSOCIATED WITH THE AND ELECTRONIC CONFIGURATIONS IN HCl, DCl, HBr, DBr, HI, and DI
No full textAuthor Institution: Center for Space Research, Naval Research Laboratory; Institute for Molecular Physics, University of MarylandThe high resolution absorption spectra of HCl, DCl, HBr, DBr, HI, and DI have been investigated in the vacuum ultraviolet. With the exception of bands identified with the b , C , and V transitions, all observed bands in HCl and DCl, and all bands in HBr and DBr below , have been correlated with states derived from the excited and configurations. Analogous states have been identified in the long wavelength spectral region of HI and DI, in addition to a few states from higher configurations. The and orbitals should correspond to and and in HBr, and and in HI, respectively. The electronic states associated with the and configurations closely approach coupling for all six molecules
USING A HIGH RESOLUTION MID-IR OPO FOR CHEMICAL DYNAMICS STUDIES OF HIGHLY EXCITED MOLECULES
No full textAuthor Institution: Department of Chemistry and Biochemistry, University of Maryland, College Park, MD 20742Quantum state-resolved energy flow dynamics are investigated for inelastic collisions of highly vibrationally excited molecules with HCl and DCl using high resolution transient IR absorption spectroscopy with a mid-IR OPO. Pyrazine molecules are optically pumped into high vibrational states with = 37,900 \wn using the quadrupled output Nd:YAG laser at = 266 nm. The state-resolved outcome of collisions is probed by measuring transient IR absorption for individual quantum states of HCl and DCl. The nascent energy partitioning among the rotational and translational degrees of freedom of the scattered HCl and DCl molecules is used to reveal how isotopic shifts in rotational energy states affect collisional energy transfer
Campus Sexual Misconduct Due Process Protections
No full textThis paper explores the present state of institutional discipline regarding sexual assaults on campus and the impact of the April 4, 2011 “Dear Colleague Letter” (DCL) issued by the Office for Civil Rights of the Department of Education on this problem. The paper then discusses the applicable Title IX standards and the procedural due process rights for the accused in campus sexual assault cases. The paper explores colleges’ responses to the DCL and means for redress for the accused under Title IX. The author argues that the DCL improperly incentivizes colleges to convict the accused, and suggests that cases of sexual assault on university campuses should be referred to courts to secure proper due process rights for both the accused and the accuser
