Rotating Raman Sample Technique for Colored Crystal Powders; Resonance Raman Effect in Solid KMnO4
Volume 25, Number 6 (Dec. 1971) Page 609-613
Kiefer, W.; Bernstein, H.J.
A simple sample technique which makes it possible to record Raman spectra of highly absorbing solids is described. The main feature is a rotating sample system containing pressed crystal powders, on which the laser beam is focused. The relative motion between laser focus and sample surface avoids heating and decomposition of the crystal powder. With this technique it is, for instance, possible to obtain a Raman spectrum of solid potassium permanganate, displaying a progression of strongly resonance enhanced overtones of the totally symmetric permanganate mode as well as a well-defined weakly enhanced spectrum for the other internal modes.
