Vibrational bands of DNA molecules from birds' erythrocytes in the weak microwave field were investigated with IR spectroscopy. Drastic changes were detected in the intensities and fine structure of C=O and PO2 bands for polarized spectra of irradiated samples of DNA molecules as compared with the reference samples in the 1700-1000 cm-1 region.

Keywords: DNA molecule, infrared and polarized spectra, vibrational bands, weak microwave irradiation.
