Two conformations of the cis-cyclohexano-8-crown-3 molecule were detected at 185 K. From relative 13 C NMR peak area measurements, the conformation with the O-CH 2 -O unit equatorial was found to be favoured by 4.4 š 0.4 kJ mol 1 . In the spectrum of the minor conformer at low temperature, a 9.6 ppm
