摘要：

The nature of radical pairs obtained by irradiation of single crystals of sterically hindered O-deuterated phenols containing 10(-3) M 2,6-di-tert-butylquinone diazide has been studied by electron-polarization-resonance (EPR) spectroscopy. A possible channel for the hydrogen-atom transfer was derived on the basis of calculated D and E values from the EPR spectra of the observed radical pairs. The thermal coefficients for the linear expansion of the crystal of deuterated phenol and diazide were measured.
