Rotational Studies of Four- and Five-Membered Ring Moleculese problems has drawn very heavily on the work of Gwinn and his collaborators on the vibrational dependence of the rotational constants and on that of Creswell and Mills for the vibrational dependence of the centrifugal distortion constants. Aspects of these problems will be discussed using molecules studied in our laboratory as examples.

These ‘very nonrigid molecules’ require special treatment when it comes to calculating the rotation-vibration energy levels. The symmetry labelling of these energy levels also poses special problems, and nuclear permutation-inversion groups (called Molecular Symmetry Groups) must

The energy path between these multiple forms usually does not pass through the planar form, but may in fact follow a lower energy route. The dynamics of the interconversion of these distinct conformational forms has been of considera
