Ultrafast IR heterodyne detected vibrational stimulated echoes with full phase information are used to obtain the vibrational correlation spectrum from a mixt. of metal-carbonyl compds. The linear absorption spectrum displays 4 peaks in the carbonyl stretching region. In the absence of knowledge of the mols. that make up the mixt., the absorption spectrum could arise from 4 mols. that each produces a single peak to 1 mol. with 4 peaks. But the correlation spectrum displays 4 peaks on the diagonal and off-diagonal peaks that make it straightforward to det. which peaks belong to a particular mol. [on SciFinder(R)]
