Abstract
We have investigated the laser-excited photoluminescence spectra of powder and aqueous solution threonine. The spectral ranges of the photoluminescence and its intensity maxima have been determined. We have measured the spectral dependence of the molar extinction coefficient of an aqueous solution of threonine. Using quantum-chemical methods, we have calculated the electron absorption spectrum, the dipole moment, and the distributions of charges on individual atoms of the threonine molecule. The calculated electron absorption spectrum has been compared with experiment.
