The use of focused laser sources, double monochromators, and pulse-counting detection makes it possible to obtain Raman spectra of crystal powders in a routine fashion. Samples as small as a few micrograms may be used. Techniques for handling crystal powder samples are described. The spectra are always accompanied by a smooth fluorescence background, on top of which the Raman lines appear. The probabilities of missing a real line or of taking a false line or of taking a false line as a real are discussed. Typical spectra of biological and other specimens will be shown.
