Notes:
The reactions D + H2 (v = 0, 1) → HD (v = 0, 1) + H have been studiedin a discharge flow reactor by CARS-spectroscopy. For H2(v = 0) molecules a rate constant of (4, 0 ± 1, 0) 10-16 cm3 s-1 is obtained at 310 K from measured HD (v = 0, 1) product yields. Keeping the degree of vibrational excitation of H2in the microwave discharge in the range of 1% from the increase of the HD (v = 0, 1) CARS signals a rate of k2a, b = (1, 0 ± 0, 4) 10-13cm3 s-1 is derived. The total consumption of H2 (v = 1) in the presence of D atoms gives a rate k2 = (1, 9 ± 0, 2) 10-13 cm3 s-1 at 310 K. The resultsare discussed in regard to previous measurements and theoretical treatments.
