Abstract
A marked dependence of e.s.r. spectral line width on surface coverage has been observed in methyl radicals stabilised on silica surfaces; at low surface coverage partial resolution of the second-order splitting is obtained, although the intensity of the lines appears not to agree with the theoretical 1 : 2 ratio; a computer simulation of this effect shows that the observed results are consistent with theory provided that both the line width and separation are considered.Keywords
