摘要：

The structure of the PO32- radical is examined by ESR spectroscopy in gamma-irradiated betaine phosphite. The ESR spectra of the PO32- radical indicate two phase transitions of betaine phosphite at T(c1) = 355 K and T(c2) = 216 K. The symmetry of the ESR spectra of the PO32- center in the paraelastic, antiferrodistortive, and ferroelectric phases of betaine phosphite is in accordance with the space groups P2(1)/m, P2(1)/c, and P2(1).
