Abstract

The polarizations of singlet–triplet transitions in molecular crystals with four molecules in the unit cell and group symmetry C^5^~2h~ are analyzed. It is shown that only transitions to factor group symmetry forbidden triplet states possess intensity and are no longer polarized perpendicular to any crystal axis.

## Abstract It is suggested that the temperature dependence of the intensity distribution among vibrational peaks in the singlet‐triplet absorption spectrum of molecular crystals can be explained by the dependence of the electronic wave function of a molecule contained in a crystal on the position
