An electron resonance study of some photochemically generated free radicals

Abstract

The abstraction of hydrogen atoms by photochemically generated t-butoxyl radicals can be used to produce steady-state concentrations of free radicals detectable by e.s.r. The hyperfine splitting constants of several new species have been measured and are discussed in terms of their probable structures. In particular, the technique provides a simple route to radicals containing heteroatoms such as Si, Ge, Sn, B, and P.
