- Abstract
Using the EPR- and IR-spectroscopy methods, we studied the conditions of formation of stable ion-radicals in the structure of calcium sulfite and determined the limits of their stability. We detected and identified the ion-radicals SO with g(iso) = 2.0055 in the initial substances, two types of thermally induced SO (with g1 = 2.0093, g2 = 2.0045, and g3 = 2.0020, and g1 = 2.0104, g2 = 2.0049, and g3 = 2.0018) when the substance was heated, and three types of mechanically induced SO (with g⊥ = 2.0036 and g‖ = 2.0022, with g(iso) = 2.0033 and ΔH = 0.1 mT and with g(iso) = 2.0031 and ΔH = 0.33 mT) when the substance was ground up.
