In this paper, the features of the Raman spectra in diamond microcrystals were investigated. The Raman spectra in microdiamonds were characterized by high intensity due to the effects of trapped radiation and total internal reflection. A characteristic line with a frequency of 1332 cm –1 and additional bands located in the overtone region of fundamental modes was registered in the observed spectra. Raman spectra in diamond-substances composites (diamond: K 2 Cr 2 O 7 , NaBrO 3 , NaNO 2 , HgI 2 , K 2 CrO 4 , PbO, KIO 3 , sulfur, iodine, stilbene, triglyceride sulfate, and POPOP) were detected.
