Improvement of simple analytical method in IRMPD experiment

Improvement of simple analytical method in IRMPD experiment. Takeuchi, Kazuo; Suzuki, Eiji (Inst. Phys. Chem. Res., Wako, Japan). Reza Kagaku Kenkyu, 8, 80-1 (Japanese) 1986. CODEN: RKAKDK. ISSN: 0558-471X. DOCUMENT TYPE: Journal CA Section: 74 (Radiation Chemistry, Photochemistry, and Photographic and Other Reprographic Processes) Section cross-reference(s): 79, 80 An improved anal. method is presented for obtaining accurate dependence of fractional conversion per pulse q on the fluence F in IR multiphoton dissocn. (MPD) expts. The new math. model is based on cumulative log-normal distribution for the dissocn. characteristics. The approx. expressions between nondimensional reaction vol. and nondimensional fluence were derived.Except for chemicals metioned above, 2837-89-0 is also used. .

DOCUMENT TYPE: Journal CA Section: 22 (Physical Organic Chemistry) Photochem. and chem. processes in multiphoton dissocn. and pulsed laser-induced pyrolysis of CF3CHClF mols. were investigated. Based on the chromatog. anal. of final products and change in concn. of difluorocarbene , a scheme for formation of the final products was suggested. It was shown that, during irradn. of the gas, products that suppressed further multiphoton dissocn. of the initial mols. and formation of difluorocarbene are accumulated in the system. The formation of noticeable amts. of the CF3CF: radicals was found to occur in the system. .
