説明

The effect of additives on the radiolytic yield of nitrogen from the radiolysis of 2, 2'-azobis-isobutyronitrile (AIBN) in benzene solution is examined. These additives have been known to quench excited benzene very effectively. Diacetyl, naphthalene, 2, 5-diphenyloxazole (PPO) and anthracene with excitation energies lower than that of AIBN in the lowest triplet state decrease the nitrogen yield. The rate constants of these compounds in quenching the excited benzene are seen to be equal for both singlet and triplet states. An anomalously high quenching rate constant is seen for anthracene, which could be attributed to the quenching of highlying excited state benzene.<br>Certain ketones with excitation energies higher than that of AIBN in the lowest triplet state also decrease the nitrogen yield with the exception of benzophenone, these compounds are all seen to provide about the same degree of reduction in nitrogen yield, in the range of concentration studied. The rate constants of self-quenching and the average life of acetone and acetophenone have been determined from kinetic studies, and the results agree with that by other investigators.<br>The effect of several charge scavengers on the nitrogen yield are also reported.
