LONGITUDINAL MUON SPIN RELAXATION IN ORGANIC RADICALS IN THE VAPOR-PHASE

The aim of this work is the study of longitudinal field relaxation for organic radicals in the gas or vapour phase, for which the technique of Muon Spin Relaxation proves to be uniquely suitable. Following on from the first such study of the muonium substituted ethyl radical in gaseous ethene [1], the present work represents the beginning of a systematic study of species of various molecular symmetries and still higher molecular weight, with a view to investigating their collisional dynamics. Preliminary data for the muonium substituted cyclohexadienyl radical in benzene vapour, and the results of tests for radical formation in acetylene and carbon monoxide, are presented.
