抄録

The history of high - pressure ESR techniques applied to solution chemistry has been surveyed briefly, and our recent investigations have been reviewed. The results are summarized as follows: (1) The rate of spin exchange reactions of nitroxides is diffusion - controlled, and the activation volume is closely related to that for diffusive processes. (2) The rates of spin - lattice relaxation for the photo - reduced products of 2, 5 - di - tert - butyl -1, 4 - benzoquinone (2, 5 - DBQ) were estimated at various pressures. (3) From the pressure effects on the ESR signal, aspects of di-tert-butyl nitroxide (DTBN) included in cyclodextrins were inferred. (4) The information on the rotational motion of spin - labeled long - chain molecules in solutions was obtained from the anisotropic ESR signals.
