The reaction D + H2 + HD + H has been investigated in two molecular beam scattering experiments. Angular and time-of-flight distributions have been measured for the initial vibrational ground state ( u = 0) at a most probable collision energy of E,, = 1.5 eV and for the first vibrational excited sta

## Abstract Absolute rate constants for the reaction of OH with H~2~S have been measured over the temperature range of 239β425 K using the flash photolysisβresonance fluorescence technique. The results showed that the rate constants deviate slightly from Arrhenius behavior but can still be represen
The reactions D + Hz (u = 0 , l ) -+ HD (u = 0 , l ) + H have been studied in a discharge flow reactor by CARS-spectroscopy. For Hz(u = 0 ) molecules a rate constant of (4,O ? 1,O) cm3 s-l is obtained at 310 K from measured HD ( u = 0 , l ) product yields. Keeping the degree of vibrational excitatio
