摘要：

Infrared absorption spectra of jet-cooled CH3Mn(CO)5 and CD3Mn(CO)5 in the region of the two strongly allowed CO vibrations have been measured using diode lasers. Analysis of the spectra yielded values for the band centers and rotational constants for parallel bands of both isotopic species, and for the perpendicular band of CH3Mn(CO)5; the latter also provided an estimate of the Coriolis constant for this vibration. The spectra were consistent with essentially free rotation of the methyl group. The rotational constants were in close agreement with those derived from electron diffraction data: however, the B-rotational constants provide a revised estimate for the axial Mn-CO bond length.
