2-dithiazolidin-2-yl radicals have been shown to be useful model compounds for detailed e.s.r. studies of rotational reorientation in liquid and frozen media. Consequently they are also potentially useful spin probes and spin labels. The e.s.r. powder spectra have been analysed and the resulting g and A tensors were used to calculate rotational diffusion correslation times, rotational energetics of activation

Thermal cyclo-addition reactions of tetrasulphur dinitride with certain alkynes generate a new series of stable freeradicals possessing the 1,3,2-dithiazolyl ring. The radicals have simple e.s.r. spectra and are potentially useful spin probes or labels. The sharpness of the spectral lines has enabled us to observe natural abundance lines from nitrogen-15, sulphur-33 and carbon-13. The presence of
