“…Comparison of the isotropic and anisotropic phosphorus hfc for the CzV and CgV radicals of PI-& and PF, indicate that their magnitude is comparable for both isomers of the &I,, and PF4 radical respectively. The same result was experimentally demonstrated by Hamerlinck et al [22,231 in a sin le c stal ESR study of the TBP-e (C,,) and TBP-a (Cj,) isomers of eBF4 radical. the l (OCZH4) 3 The calculations predict larger hfc for the CaV isomers, whereas the reverse was found experimentally (Fig.…”
