Abstract: | During the photopolymerization of perdeuterated PTS diacetylene single crystals at low temperatures, excited quintet states (S = 2) are observed Nine ESR transitions per quintet were detected. They are analyzed in terms of a spin hamiltonian for S = 2. They are due to bicarbenes of, probably, short oligomers. |
