Abstract

Polarized low-temperature absorption spectrum of centrosymmetric Pr3+-antipyrene tri-iodide single crystal has been recorded. Electronic transitions to the 1D2 and 3P0,1,2 states have been found to be forbidden. Associated vibronic lines have been analyzed. Lattice, metal-ligand, and ligand internal (such as C=0) modes appear in the spectrum. Crystal field parameters have been evaluated and found to be large. Participation of ∏ electrons in the bonding has been suggested.
