The 19F nuclear magnetic resonance spectra of four halogenated ethanes, CF2BrCFBrCl, CF2 ICFCl2, CF2ClCFICl and CF2BrCFBrSO2F over a range of temperature (130–350°K) are described. Individual-rotamer and time-averaged chemical shifts and coupling constants are given. The possibility of theoretical interconversion of individual and averaged parameters is considered.
