TIME EVOLUTION OF SHORT-LIVED MOLECULAR SPECIES OBSERVED BY INTRACAVITY LASER ABSORPTION SPECTROSCOPY
No full textAuthor Institution: Laboratoire de Spectcometrie Physique Universite Scientifique et Medicale de Grenoble BP68 38042, Saint Martin d'Heres; Department of Chemistry, Davidson College, Davidson; Department of Chemistry, Syracuse University SyracuseWe report the feasibility of using CW intracavity laser absorption spectroscopy (ICLAS) as a probe in detecting transient species generated by pulsed laser photolysis. The method of detection uses a time-generated CW laser beam and time-resolved spectra which are delayed with respect to the photolysis pulse. Variable time delays and a constant generation time have been used to detect the time dependence of the absorbing species at times as short as a few microseconds. We applied the technique to the study of the time evolution of the formation of the free radical HCO generated by photolysis of gas-phase acetaldehyde at pressures down to tens of mtorr. We have also found that the ultimate sensitivity of the ICLAS technique is limited mainly by the mechanical stability of the cavity. M. Chenevier, M. A. Melieres, F. Stoeckel, to be published G. H.

VIBRONIC ASSIGNMENTS IN THE ABSORPTION SPECTRUM OF GLYOXAL BY TIME-RESOLVED SVL FLUORESCENCE
No full text E. Photos and G. H. Atkinson, Chem. Phys. Let. 36, 34 (1975).""This work was supported by U.S. Amay Research Office, the Am. Chem. Soc., and the Research Corporation.""Author Institution: Department of ChemistryFluorescence spectra from single vibronic levels (SVL) In glyoxal vapor have been analysed in order to (1) experimentally establish the vibrational modes populated during absorption transitions and (2) provide information about excited-state structure through the analyses of Franck-Condon factors. Since such spectra are comprised of ground-state vibrational frequencies which are well established from infrared and Raman spectroscopy, these data can often provide unique identification of absorption transitions. Time-resolved SVL (TRSVL) techniques utilize box car integration and pulsed laser excitation to observe emission before a significant degree of collisional perturbation can redistribute excited-state energy to vibrational modes not initially-populated in TRSVL techniques have been used to reveal the activity of for the first time and to confirm more than twenty other vibronic transitions. A low resolution analysis of fluorescence band contours is included in this work. A Franck-Condon analysis of these fluorescence spectra has also been performed and provides new information about the geometry of the state
TIME-RESOLVED RESONANCE RAMAN () SPECTROSCOPY

This work was supported by the NSF.""Author Institution: Department of Chemistry, Syracuse UniversityExperimental techniques designed to obtain resonance Raman spectra of short-lived intermediates during photolytically-induced reactions will be described. These methods use high peak power ( 1 MW), pulsed laser excitation to generate Raman scattering and intensified vidicons as multi-wavelength detectors. The time resolution available extends from to several seconds. Studies of labile biophysical systems (oxyhemoglobin and cytochrome c) have demonstrated that resonance Raman spectra obtained with such high peak-power excitation exhibit no saturation or denaturation Results on the reaction intermediates in the ligation of hemoglobin and the oxidative photocyclization of substituted amines to carbazoles will be presented to illustrate the capabilities of these techniques
Search for Diboson resonances in 8 tev and 13 tev proton-proton collisions at the large hadron collider with the atlas detector
No full textThis thesis documents two searches for Diboson Resonances which were performed using data collected in 2012, 2015 and 2016 by the ATLAS detector at the Large Hadron Collider. Three benchmark models are tested: a model predicting the existence of a new heavy scalar singlet, a simplified model predicting a heavy vector-boson triplet (V ′), and a bulk Randall-Sundrum model with a heavy spin-2 graviton (G∗). Neither of these searches found evidence of any resonance, and exclusion limits are set on σ(pp → V ′) and σ(pp → G∗).
For the 2012 ATLAS data, searches are performed for the G∗ and the W′. The sample corresponds to an integrated luminosity of 20.3 fb−1 proton-proton collisions with a center of mass energy √s = 8 TeV. This search looks for the decay channels G∗ → WW → lνjj and W′ → WZ → lνjj. No evidence for resonant diboson production is observed, and resonance masses below 760 GeV and 1490 GeV are excluded at 95% confidence level for the spin-2 Randall–Sundrum bulk graviton G∗ and the spin-1 extended gauge model W′ boson respectively.
For the 2015 and 2016 ATLAS data, searches are performed for the G∗ and the V ′ and a heavy scalar. The sample corresponds to an integrated luminosity of 36.1 fb−1 proton-proton collisions with a center of mass energy √s = 13 TeV. This search looks for the decay channels G∗ → V V , scalar → V V and V ′ → V V/V H/dilepton. The V V and V H dibosons then decay into qqqq, ννqq, lνqq, llqq, lνlν, llνν, lνll, llll, qqbb, ννbb, lνbb, or llbb which are all combined (14 channels). No evidence for resonant diboson production is observed, and resonance masses below 2300 GeV are excluded at 95% confidence level for the spin-2 Randall–Sundrum bulk graviton G∗. Resonance masses below 5500 GeV and 4500 GeV are excluded at 95% confidence level for the heavy vector triplet in a weakly coupled scenario and a strongly coupled scenario respectively. No limits are extracted for the heavy scalar.Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2021-08-01The student, Markus Atkinson, accepted the attached license on 2019-07-04 at 17:54.The student, Markus Atkinson, submitted this Dissertation for approval on 2019-07-04 at 18:07.This Dissertation was approved for publication on 2019-07-05 at 16:01.DSpace SAF Submission Ingestion Package generated from Vireo submission #14175 on 2019-11-26 at 13:04:28Made available in DSpace on 2019-11-26T20:49:21Z (GMT).

Rapid recycling of coral mass-spawning products in permeable reef sediments.
No full textDuring the annual synchronous release of gametes by corals, a large amount of energy-rich organic material is released to the reef environment. In November 2001, we studied a minor spawning event at Heron Island in the Great Barrier Reef (GBR), Australia. Laboratory experiments showed that egg release by the staghorn coral Acropora millepora amounted to 19 ± 15 g dry mass (mean ± SE, n = 8) per m2 coral surface. Carbon content reached 60.1 ± 4.0% and nitrogen content 3.6 ± 0.4% of the egg dry mass. During this minor spawning period, Acropora corals from the reef crest released 7 g C and 0.4 g N as eggs m-2 reef. In situ experiments (n = 11) using stirred benthic chamber measurements revealed that the sedimentary O2 consumption (SOC) of the lagoon sediments increased sharply immediately after the coral spawning. Extreme SOC rates of 230 mmol O2 m-2 d-1 were reached 2 d after the event, exceeding the pre-spawning rate by a factor of 2.5. This maximum was followed by a steep decrease in SOC rates that gradually levelled off and reached pre-spawning values 11 d after the event. The immediate and strong response of SOC shows that the coral spawning event provides a strong food impulse to the benthic food chain. Our results demonstrate high decomposition efficiency of permeable carbonate reef sands and underline the role of these sediments as a biocatalytical recycling system in the oligotrophic reef environment
