Spinning-Cell FT-Raman Spectroscopy: Application to Crystalline Octacarbonyldicobalt(0), Co2(CO)8

Abstract

Raman spectrum of crystalline octacarbonyldicobalt(0), Co2(CO)8, has been successfully obtained for the first time by using a Fourier transform instrument together with a spinning sample cell to avoid decomposition of Co2(CO)8 upon exposure to the near-IR laser radiation used to excite the spectrum. Previously, only limited regions of the Raman spectrum could be obtained with visible laser excitation because of extensive sample burning. The new FT-Raman results, combined with the related IR data from the literature, provide a better description of the vibrational properties of this important binary metal carbonyl complex.
