Excited Electronic States of Crystalline Benzene

摘要

In the present paper, the excited electronic states of crystalline benzene are examined with the use of exciton theory. Ionhyphen;pair exciton states are considered and it is shown that these may play a considerable role in determining the observed spectra. Their effect on the lowest triplet state is also considered. The results of the analysis are in agreement with the available experimental data and are also consistent with the analysis of the spectrum of crystalline naphthalene.
