Abstract
X-Irradiation of single crystals of carboxymethyltriphenylphosphonium chloride produces the corresponding oriented phosphorane radical-cation Ph3[graphic omitted]ĊH·CO2H. The spectrum has been analysed to yield the hyperfine coupling tensors of the 1H and 31P nuclei and the g-tensor. These values are discussed in terms of the possibility of delocalisation of the unpaired electron in a 3d orbital of the phosphorus atom.Keywords
