J. 235, 52 (1980).Author Institution:Radiative association of C++HC^{+} + H is Che principal formation mechanism of CH+CH^{+} in diffuse interstellar clouds. Current description of this process relies on model calculations using theoretical potential energy curves for the X1Σ+X^{1}\Sigma^{+} and A1πA^{1}\pi; states of CH+CH^{+}, but cannot account for the observed abundance of this ion.1ion.^{1} We are attempting to determine experimentally the potential curves for these states in the regions relevant to radiative association by observing the reverse process: predissociation of CH+CH^{+} through shape resonances In the A1πA^{1}\pi state. A mass selected beam of CH+CH^{+} ions is merged with a laser beam over a distance of 60 cm. The appearance of fragment C+C^{+} ions from the photodissociation of CH+CH^{+} is studied as a function of both wavelength and production kinetic energy. The wavelength dependence is studied either by employing a tunable dye laser or by Doppler tuning a fixed ion laser frequency by variation of the ion beam velocity. Our Initial measurements of the predissociation of CH+CH^{+} using ion laser lines in the region of 3500 {\AA} are described in Ref. 2. We have extended these measurements to 6471 {\AA} using both ion laser lines and a tunable dye laser. Predissociations of rotationally quasi-bound levels of the A1πA^{1}\pi state are observed throughout this wavelength range. Assignment of the transitions has been made on the basis of the observed transition frequencies, Photofragment kinetic energies, and predissociation lifetimes. Several significant discrepancies are found between the photodissociation measurements and the predictions of theory, demonstrating that the potential energy curve of the A1πA^{1}\pi; state is less attractive at large internuclear distances and somewhat shallower than predicted

    1^{1} B.A. Huber, T. M. Miller, P.C. Cosby, H. D. Zeman, R. L. Leon, J. T. Moseley, and J. R. Peterson, Rev. Sci. Instrum. 48, 1306 (1977). Research supported by AFOSR.Author Institution:Photodissociation of CH3I+CH_{3}I^{+} to CH3+CH_{3}^{+} is observed using the SRI laser-ion coaxial beams photo-fragment spectrometer. 1^{1} The CH3I+CH_{3}I^{+} ions are produced by electron impact on CH3ICH_{3}I, accelerated to 4 keV, mass selected, and merged with a laser beam. The appearance of CH3+CH_{3}^{+} photofragment ions is detected as a function of both laser wavelength and product ion kinetic energy. Predissociation of CH3I+CH_{3}I^{+} in eight vibronic bands of the A~2A1;X~2E1/2\tilde{A}^{2}A_{1} \leftarrow; \tilde{X}^{2}E_{1/2} system is observed at moderate resolution (0.5cm10.5 cm^{-1}) over the wavelength range of 6100 – 5700 {\AA}. Kinetic energy analysis of the photofragments suggests the bands correspond to progressions in the C – I stretching frequency of the A~\tilde{A} state and that two or more vibrational levels of this state lie below the CH3++I(2P3/2)CH_{3}^{+} + I(^{2}P_{3/2}) dissociation limit. Measurements in portions of these bands at high resolution (0.003cm10.003 cm^{-1}) reveal a high density of transitions (>10(> 10 transitions/cm1cm^{-1}) and a pre-dissociation lifetime of >> 5ns. The rotational fine structure of the bands is fully resolved in the spectra. Photofragment kinetic energy measurements for individual rotational lines show the release of discrete amounts of kinetic energy and suggest a nonstatistical distribution of rotational energy in the dissociations
