Key Points

To measure vibrational-to-vibrational (V→V) energy transfer rates from excited molecular hydrogen to various simple gas molecules using stimulated Raman vibrational fluorescence.
Utilized a stimulated Raman vibrational fluorescence technique to excite Raman-active vibrational modes in molecular hydrogen (H2).
Monitored vibrational energy transfer into additive gas mixtures at total pressures down to 70 torr.
Determined V→V rate constants (sec⁻¹ torr⁻¹) for rapid transfer partners: HCl at 1510 ± 210, DCl at 689 ± 30, CO2 at 497 ± 30, and N2O at 462 ± 14.
Measured V→V rate constants (sec⁻¹ torr⁻¹) for slower transfer partners: HBr at 224 ± 18, DBr at 212 ± 36, NO at 42 ± 17, 12CO at 12.3 ± 9.5, and 13CO at 9.7 ± 1.9.
