LOWEST EXCITED STATES REORDERING IN (ARENE)M(CO)<sub>3</sub>, WHERE M = Cr or W, COMPLEXES

A series of electronic spectral changes was observed when (arene)M(CO)3 complexes (where arene = benzene, chlorobenzene, phenyltrimethylsilane, acenaphthene, mesitylene, and M = Cr or W) were irradiated with 313 nm light in benzene solution at 298 K in the presence of excess pyridine. These photolys...
