Abstract
A technique for studying the photoluminescence spectra of pharmaceuticals (paracetamol, analgin) was developed for single- and two-photon excitation with a pulse-periodic laser. The technique is based on the fiberoptic recording of photoluminescence spectra using a small-size spectrometer, quartz light guides, and mini cavity cuvettes, which makes it possible to compare the analyzed spectrum with the spectrum of the reference substance.
