| Abstract: | From proton magnetic resonance spectra of TTF and TCNQ partially oriented in nematic liquid crystal solvents the ratio of length to width of the proton rectangle is 3.124 ± 0.03 for TTF and 1.765 ± 0.024 for TCNQ. Values of JCH obtained for TTF dissolved in d6-acetone, are JCH = 187.9 ± 0.3 Hz, JCCH = 6.7 ±0.1 Hz and JCSCH = 9.0 ±0.2 Hz. |
