Effect of Heavy Atoms on the Doublet Components of the Phosphorescence Spectrum of Triphenylene in Carbon Tetrachloride

Intensity distribution and kinetics of the doublet components of the phosphorescence spectrum of triphenylene in a frozen solution of carbon tetrachloride are analyzed. It is shown that the effect of heavy atoms (chlorine) depends on the orientation of triphenylene molecules in the crystal lattice o...

Description
Summary:Intensity distribution and kinetics of the doublet components of the phosphorescence spectrum of triphenylene in a frozen solution of carbon tetrachloride are analyzed. It is shown that the effect of heavy atoms (chlorine) depends on the orientation of triphenylene molecules in the crystal lattice of carbon tetrachloride differently for spin-forbidden and symmetry-forbidden transitions.
