摘要: A single crystal of deuterated malonic acid has been studied at room temperature by deuteron magnetic resonance (DMR). An analysis the results yielded four electric quadrupole interaction tensors with coupling constants 181·9 ± 0·2, 179·9 168·1 0·2 and 165·0 2·0 kHz. The corresponding values for asymmetry factors were 0·103 0·002, 0·125 0·038 0·002 0·01 0·03. angles between directions maximum principal components first two hydrogen bond predicted from reported structure are less than 4°. In addition, intermediate magnitude same within 10° perpendiculars to planes formed carboxyl bonds. Thus, an application Chiba's rules permits a reasonable assignment tensors. angle remaining tensors, that these form ...
