Summary:A LIF technique that employs a precisely positioned, varying view, field has been developed to give quantitative measurements for vibrational relaxation rates in supersonic jets of I 2(B, ν′=43) seeded in Ar, N 2 and CO. The multiple vibrational quantum transfer effect is very pronounced. In particular, for N 2 and CO, the most probable relaxation pathway is no longer the Δν=−1 process, which apparently violates the energy gap law. These observations are adequately explained by invoking the formation of a metastable complex.
