Symmetry hydrocarbon radical cations

Another crucial finding was the realization that rapid spin-lattice (Ti) relaxation in the high-symmetry cycloalkane radical cations precludes their detection with optically-detected magnetic resonance (ODMR) [39-48], the technique which was routinely used to study radical cations in radiolysis of hydrocarbons [38, 50]. For example, trans-decalin + isolated in room-temperature cyclohexane has Tj 7 ns [50] while typical solute radical cations have Ti 1 ps. Since it takes several tens of nanoseconds to flip the electron spin with the microwave radiation (which is required for the magnetic resonance detection) radical cations of some cycloalkanes cannot be detected by ODMR. [Pg.180]
