Laser Activation of Oxygen in Aerated Solvents. Measurement of the Absorption Spectra of Oxygen Dissolved in Aerated Solvents under Natural Conditions

The results of authors’ studies of the photochemical activity and phosphorescence of oxygen molecules upon direct laser excitation of oxygen in aerated organic solvents and water have been shortly summarized. The absorption spectra of oxygen dissolved in these media at normal pressure and temperature have been obtained in the spectral range of 600–1300 nm. The information received is of fundamental importance for spectroscopy of molecular oxygen and elucidation of the role of oxygen as a photoreceptor triggering the biological action of laser radiation.
