摘要：

Photolysis of 2,2'-dimethylbiphenyl-4,4'-diazide in a glassy matrix at 77 K gives first a mononitrene ESR peak (\D/hc\ = 0.95 cm-1), followed by production of a lower field peak attributable to a twisted biphenyl-4,4'-dinitrene (\D/hc\ = 0.93 cm-1), in which two nitrene moieties are electronically isolated from one another by torsion.
