Abstract

Abrupt peaks in the graphs of phosphorescence lifetime versus temperature were observed in solid (Bu₄N⁺)₂MnBr^2-₄ at temperatures at which thermal transitions were also observed. The corresponding MnCl^2-₄ system displayed a completely different behavior. The results are interpreted as reflecting changes in the rates of the radiationless decays, in turn reflecting the impediment of noncentrosymmetric vibrations.
