Title :Local Stark Mixing in the Phosphorescent Processes of p-Benzoquinone
Authors :Miyagi, Yusei
Authors alternative :宮城, 雄清
Issue Date :Mar-1993
Abstract :The phosphorescence spectra of p-benzoquinone are very sensitive to environments and electric fields since the molecule have small energy gaps between the first and second excited triplet states. The variable vibronic pattern from solvent to solvent is a manifestationof perturbation between the two triplet n π* states. The calculation of the local field strength of dipolar environments indicates that the effective electric fields coming from the environmental dipolar pertrubations in polar solvents or binary-mixed nonpolar solvents are~10^6 V/cm in order of magnitude in external bulk scales. It is also demonstrated that these rather intense fields lead the drastic increments of the phosphorescence origin band due to the local Stark mixing between ^3B_<1g>(n,π*) and ^3A_u(n_1π*). Coupling matrix element obtained due to the solvent Stark fields is 212 cm^<-1>.
