Radiation mechanisms—VIII. Radiolysis of borohydride ions in aqueous solutions. An E.S.R. study

Abstract

Radiolysis of frozen aqueous or methanolic glasses containing sodium borohydride gave E.S.R. features characteristic of ·BH₃⁻ as the major radical product. These radicals were strongly associated with the solvent lattice in contrast with their behaviour in the parent salt. Additional E.S.R. features separated by ca. 200 G are assigned to BH₄, but since this spectrum could never be obtained in the absence of the intense BH₃⁻ features, this assignment is tentative.
