A. Hudson et al., FREE-RADICALS FROM BIOGENIC VOLATILE ORGANIC-COMPOUNDS (VOCS) - AN ELECTRON-SPIN-RESONANCE INVESTIGATION, Perkin transactions. 2, (12), 1995, pp. 2091-2093
Electron spin resonance has been used to characterise free radicals fo
rmed by the reactions of photochemically generated tert-butoxyl radica
ls with alpha-pinene, beta-pinene, alpha-terpinene, gamma-terpinene, c
ar-2-ene, car-3-ene and limonene. The spectra have been interpreted us
ing computer analysis and simulation and assigned to substituted cyclo
hexenyl or cyclohexadienyl radicals formed by abstraction of a hydroge
n atom from the parent terpene.
