In order to elucidate chemical structure of alumino-p-aminosalicylic acid, single crystal of calcium alumino-p-aminosalicylate was prepared and its crystallomorphological and optical characteristics were examined. Examination of the presence or absence of the center of symmetry in this salt molecule was made through infrared absorption spectrum and Raman effect. Presence of the spectra with the same frequency in the Raman and infrared spectral measurements indicated the absence of a center of symmetry in the molecule of alumino-p-aminosalicylic acid.
