[Spectral characteristics of riboflavin tetrabutyrate].
The paper deals with the results of a spectroscopic investigation of riboflavin tetrabutirata in solutions of various polarity. The fluorescent and polarized excitation and emission spectra, absorption spectra are obtained; the quantum yield of fluorescence in the ethanol and glycerol solutions is determined. The character of the absorption and fluorescence spectra, the degree of polarization and the quantum yield of fluorescence are established to be strongly dependent on the solution polarity.
