Abstract—
Formation of hydrated electrons in water exposed to thermal electromagnetic radiation and influence of temperature (9–75°С) and D2O concentration (0–100 vol %) on their optical absorption spectra are investigated. Two distinct bands at 738 and 836 nm are observed in the initial spectrum. The spectra at temperatures from 10 to 80°С have two isosbestic points and four Gaussian components with domination of the component at 720 nm. As temperature rises, absorption increases and bands shift to the short-wave region. As the D2O concentration increases, the absorption spectrum intensity considerably decreases to its complete disappearance in 100% heavy-hydrogen water.
