Abstract
DESPITE the very numerous investigations of the electron spin resonance spectra of DPPH (αα-diphenyl-β-picrylhydrazyl) a number of perplexing problems remain. Those relating to its behaviour in various solvents are important because DPPH is used very commonly as a standard for concentration measurements in electron spin resonance and as a radical ‘scavenger’ in the examination of radiation chemistry.
