reported to be the energy difference between the lowest vibrational levels, but its calculation from measured microwave intensities at a single temperature suggests that it may be a free-
energy difference, presumably corrected for the two-fold statistical factor favoring the C-O-C-C gauche conformer; no later report on this measurement appears to have been made.
