[Abstract]

We investigated the difference in reactivity of O(1D) towards two types of hydrogen atoms in CH3OH. Infrared emission of vibrationally excited OH and OD products was recorded with a step-scan time-resolved Fourier-transform infrared spectrometer. In the reaction of O(1D) + CD3OH, the rotational distribution of OD is nearly Boltzmann whereas that of OH is bimodal. The product ratio is [OH]/[OD] ~ 1.56. In the reaction of O(1D) + CH3OD, the rotational distribution of OH is nearly Boltzmann whereas that of OD is bimodal, with a product ratio of [OH]/[OD] ~ 0.59. Reaction mechanism will be discussed.

We took advantage of the diminished cage effect of p-H2 to produce free radicals and protonated species. Upon photolysis of the Cl2/C6H6/p-H2 (1/1/1500) sample at 3.2 K with light at 365 nm, new lines are assigned to 6-chlorocyclohexdienyl (s-C6H6Cl) based on the observed deuterium isotopic shifts of s-C6D6Cl and comparison with theoretical calculations. If time permits, IR spectra of C6H7, C6H7+, a-C10H9, b-C10H9, a-C10H9+, and b-C10H9+ will also be discussed.
