Oxygen Induced Triplet State Transitions of Benzene in Cryogenic Solutions.

Abstract:

A new way of investigating the oxygen induced triplet state transitions of simple organic molecules is presented. The method involves dissolving the organic along with oxygen in hydrocarbon liquids such as propane, ethane, or propene. Both triplet Blu from singlet Alg and triplet Elu from singlet Alg transitions of C6H6 and C6D6 are studied in this work. These results indicate that both triplet states and their vibrational spacings are quite sensitive to the environment. The suggested dominant feature of the triplet Blu state of C6H6 is nu8 916 per cm of e2g symmetry. Observed triplet state intensity enhancement is believed to be due to a non-statistical oxygenbenzene van der Waals complex formed in the low temperature liquid. Author
