Collision Partner

Quenching of I2* [Formula: see text] (υ′ = 26) is shown to take place to the exclusion of vibrational-energy transfer in iodine at pressures up to 19 mm. A possible quenching mechanism involving sensitized predissociation of the collision partner is described. Vibrational transfer in collisions with H2 and D2 is found to occur at less than every gas kinetic collision. Arguments on general grounds are put forward to support this result, which conflicts with that of earlier workers. Increase in the mass of the isotope is found to bring about increased efficiency of vibrational transfer.

First Time

The CARS (coherent anti-Stokes Raman scattering) technique has been used for the first time to observe directly the vibrational energy transfer between nitrogen N2 (X1Σ, ν = 1, 2) and carbon dioxide. The transfer-rate constants were determined as (1.0 ± 0.1) × 1011 cm3 mol−1 s−1 and (1.7 ± 0.4) × 1011 cm3 mol−1 s−1 for N2(ν = 1) and N2(ν = 2), respectively.
