โœฆ Synopsis

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 excitation of Hz in the microwave discharge in the range of 1% from the increase of the HD (u = 0,l) CARS signals a rate of k,,,, = (1,O * 0,4) cm3 s-' is derived. The total consumption of Hz(u = 1) in the presence of D atoms gives a rate kz = (1,9 -C 0,2) cm3 s-' at 310 K. The results are discussed in regard to previous measurements and theoretical treatments.
