摘要：

The resonance Raman and electronic absorption spectra of M(CO)4DAB (M = Cr, Mo, W; DAB = 1,4-Diazabutadiene) in alkane solutions or glasses at temperatures below 200 K indicate the existence of a second isomer in which the M(CO)4 moiety has a pseudo C4ν symmetry. In polar solvents a continuous shift of the CT band is found when the temperature is lowered. This thermochromism is caused by an increase of the solvatochromism at low temperature. © 1979.
