Abstract

Vibrational bands of DNA molecules from birds' erythrocytes, as well as Dunaliella viridis alga cells and Escherichia coli bacteria clinical strains in the weak microwave field were investigated with IR spectroscopy. Drastic changes were detected in the intensities and fine structure of C equals O and PL₂ bands for polarized spectra of irradiated samples of DNA molecules as compared with the reference samples in the 1700-1000 cm^-1 region. No essential changes were detected in the IR spectra in the region of PO₂ bands of DNA for the Escherichia coli, irradiated by the weak electromagnetic field, but essential redistribution of intensities and change in halfwidths of the PO₂ symmetrical bonds were detected for Dunaliella viridis alga cells.
