✦ Synopsis

Polarized absorption spectra of single crystals of Ca2PO4Cl doped with V(V) ions have been measured at liquid-helium temperature. Only one broad and \ery intense band is observed from 30000 to 45000 cm-' _ hTdsymmetry itisassigned as a charge-transfer transition lT* + 1 and 'E. Al. Under the Td + Dzd site perturbation, the excited state 'T2 is split into 'Bl
