We report H/sub 2/ V..-->..V transfer rates to a number of simple molecules using a stimulated Raman vibrational fluorescence technique. The additive gases and respective rate constants (sec/sup -1/ torr/sup -1/) are HCl(1510 +- 210), DCl(689 +- 30), CO/sub 2/(497 +- 30), N/sub 2/O(462 +- 14), HBr(224 +- 18), DBr(212 +- 36), NO(42 +- 17), /sup 12/CO(12.3 +- 9.5), and /sup 13/CO(9.7 +- 1.9). The ease of experimental data collection, even at total pressures as low as 70 torr, shows the utility and general application of this approach in the excitation of Raman active vibrations in simple systems.
