Abstract
Electronic absorption spectra of a range of molybdenum(V) complexes and [WOCl4(H2O)]– have been measured in the temperature range 4.2–300 K and in the energy range 4 000–40 000 cm–1. The absorption bands below 18 000 cm–1 have been assigned to the one-electron promotion dxy*→dxz*, dyz*. Bands in the visible region have been classified as type I (dxy*→dx2–y2*) or type II (in-plane ligand-to-metal charge transfer). Assignments of the absorption spectra of the chromophores MoO3+, VO2+, WO3+, MoN2+, RuN3+, and OsN3+ have been compared to produce a self-consistent assignment.Keywords
