Solid-state mid- and near-IR photoacoustic (PA) spectra have been measured at room temperature for the group 6B metal(0) mixed carbonyl-t-butylisocryanide complexes M(CO)[sub 6[minus]n](CN[sup t]Bu)[sub n] (M = Cr, Mo, W; n= 1-3). Vibrational assignments are proposed for many of the observed bands. The PA spectra in the near-IR region (4600-3600 cm[sup [minus]1]), where the binary v(CN) and v(CO) overtones and combinations absorb, are useful spectral fingerprints for these organometallic complexes. 20 refs., 3 figs., 3 tabs.
