Rate coefficients and products were determined for the title reactions employing a drift tube mass spectrometer apparatus. The implications of these reactions for the ion chemistry of the stratosphere is discussed.
Using 2 + 1 multipho ton ionization, NH; is prepared in sclcctcd levels of the "2 bending mode (v = O-7) and the NH:(u) + Da reaction is studied as a function of the center-of-mass collision energy (l-10 eV). The exchange channel (NH2D\*+ HD or H + D) is enhanced by ion vibrational ehcitation wherex
The title reaction fomls electronically excited HSO6 'A') directly, with considerable vibrational and rotational escitarion as well. The inrernal excitation of the HSO fragment is the maGrnum possible consistent with the concurrenr formation of an O~('A$ molecule as rhc other reaction product. The o
An analysis of the primary photodissociation products resulting fro-m the 193 nm photolysis of HSCO is reported\_ The major fngments are NH(a IA, u' = 0) and CO(X '~3. Reaction of NH(a 'A) with 02 and with HIiCO produces only nonemissive products. A rapid E-E, V energy transfer occurs for collisions
