Abstract

The method of time-resolved magnetic field effect was applied to measure the spin–lattice relaxation time T1 for radical cations of a number of cycloalkanes in n-hexane solution at room temperature. The T1 value for the Jahn–Teller active cyclohexane radical cation was found to be approximately 9 ns which was substantially shorter than typical values for organic radical ions. Based upon the similarity of effects that various factors had on the spin–lattice relaxation rate of the cyclohexane radical cation and the benzene radical anion it was proposed that the spin–orbital interaction made the predominant contribution to the relaxation of both radicals.

Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
