Abstract
The far-infrared spectra of molecules of the general structure where X, Y = O or $CH_{2}$ have been investigated. The lowest frequency mode, the ring-puckering vibration, gives rise to a series of Q branches which may be interpreted as single quantum jumps within a single-minimum asymmetric potential function of the form v(x) = $ax^{4}$ + $bx^{2}$ + $cx^{3}$, where x is the ring-puckering coordinate and a, b and c are all positive.
