Abstract:

Use of a rotating solid sample device in the Raman examination of deeply colored highly absorbing samples was investigated. A wide variety of inorganic, organic, and metallorganic compounds ranging in color from pale yellow to orange-red and black were studied using 4880 Å or 5145 Å argon ion excitation. Good quality spectra were obtained from solid samples which previously were either destroyed by conventional static excitation or required defocusing or attenuation of the laser beam with attendant energy losses. The technique appears to offer a general solution to the problem of highly absorbing samples which decompose because of localized overheating by absorption of the source radiation. In some cases, resonance Raman effects may be studied.
