19F NMR chemical shifts and coupling constants are reported for 215 compounds. For 77 of these compounds, 1H NMR spectral data are also given. Long-range couplings, including 8J(F,F) and 5J(F,H), are reported. The complexity of halocarbon spectra owing to the presence of rotational isomers, asymmetric centers, long-range couplings, and chlorine isotope effects are illustrated, and the methods used for analyzing such complex spectra are briefly discussed.
报道了215种化合物的19F核磁共振化学位移和耦合常数。其中77种化合物还给出了1H核磁共振光谱数据。报道了包括8J(F,F)和5J(F,H)在内的远程耦合。阐述了由于存在旋转异构体、不对称中心、远程耦合和氯同位素效应而导致的卤代烃光谱的复杂性,并简要讨论了分析此类复杂光谱所使用的方法。
