✦ Synopsis

Low-temperature 13C NMR spectral data have been obtained for equatorial and axial methyl-, ethyl-and isopropylcyclohexane using a high-temperature cryogenic trapping technique. -C chemical shi€t differences between major and minor conformations of each compound are discussed in terms of chemical shift theories. A convenient synthesis of deuteriated dichlorofluoro-and difluorochloromethane, which are excellent low-temperature NMR solvents, is also presented.
