摘要：

Single-crystal monomers of 5, 7-dodecadiyne-1, 12-diol bis(phenylurethane) X-ray irradiated at 77 K give rise to an ESR spectrum at 77 K consisting primarily of lines due to radical pairs along with some weaker lines due to S = 1/2 radicals. The radical pair is a biradical of a diacetylene dimer with D = 732 G and E = 26.5 G and appears to be the initiator of solid-state polymerization of X-ray irradiated TCDU crystalsat low conversion. © 1979, American Chemical Society.
