英文摘要: A LIF technique that employs a varying view field has been developed to give quantitative measurement for the vibrational relaxation rates of I-2 B(nu ' = 43) state in supersonic jets. The data for Ar, N-2 and CO are obtained for the first time. The results have shown that the measured vibrational relaxation rates in cold jets bear an inverse tempeature dependence. For He and H-2 carrier gases, the dominant relaxation process is the usual Delta nu = -1 process. For Ar, N-2 and CO, however, the most probable relaxation pathway is no longer Delta nu = -1 process, which apparently violates the energy gap law. These observations are adequately explained by a metastable complex formation mechanism.
