A further investigation of the polarized single-crystal electronic absorption spectrum of [AsPh4][CrOCl4]
Abstract
Polarized single-crystal electronic absorption spectra have been recorded for [AsPh4][CrOCl4] at 77 and 4.2 K in the energy range 4 000–40 000 cm–1. Three band systems have been identified and have been assigned to the three possible d–d transitions in C4v symmetry. The previously unreported band system originating at ca. 20 000 cm–1 has been assigned to the one-electron promotion dxy→dz2.
