RADIATION-CHEMICAL BEHAVIOR AND SPECTRAL CHARACTERISTICS OF SOLVATED ELECTRONS IN LIQUID TRIALKYL PHOSPHATES

Spectral-kinetic properties of solvated electrons (e(s)) were investig ated in eight trialkyl phosphates (TAP) by nanosecond pulse radiolysis . It was found that the main reaction determining the radiation-chemic al behavior of e(s) is their dissociative attachment to TAP molecules in all of the solvents studied. The parameters of optical absorption b ands of e(s) were measured; the form of spectral curves was analyzed. The results are discussed in terms of a modem view of dissociative e(s ) attachment reactions and the role of molecular structure in the dete rmination of the localized state of an excess electron.
