The resonance Raman and electronic absorption spectra of M(CO)JIAB (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), moiety has a pseudo C,, symmetry. In polar solvents a continuous shift
