摘要：

A study is made of the effect of added octane-d18 on the ESR spectrum of heptane observed after gamma-irradiation at 77 K. It is found that the presence of deuterated octane in heptane upon gamma-irradiation results in a substantial increase in the relative contribution of 1-heptyl radicals to the paramagnetic absorption. This increase is due to the occurrence of proton transfer from heptane radical cations to deuterated octane, which is considerably more efficient than to the heptane matrix. An explanation based on solid-state structure and proton affinity data is presented. The results indicate that proton transfer may be an important alternative to hole transfer in irradiated solid binary alkane systems.
