dc.description.abstractVarious examples of perturbations in the vibration-rotation-torsion energy levels of an ethane molecule exhibiting internal rotation splittings are discussed, both from the point of view of the point group $D_{3d}$, appropriate when internal rotation tunneling effects cannot be observed, and from the point of view of the group $G_{36}{^\dag}$, appropriate when internal rotation tunneling in ethane leads to observable splittings in the spectrum. It is found for perturbations allowed in both $D_{3d}$ and $G_{36}{^\dag}$, that each of the two torsional components of the perturbed $D_{3d}$ vibration-rotation level can in principle interact with a ""corresponding"" torsional component in the perturbing vibration-rotation level. It is found for perturbations forbidden in $D_{3d}$ but allowed in $G_{36}{^\dag}$, which all occur between $D_{3d}$ vibrational levels of different g,u parity, that only one of the two torsional components of the perturbed $D_{3d}$ vibration-rotation level can interact with a corresponding torsional, component in the perturbing vibration-rotation level. Some of the perturbations examined give intensity to otherwise forbidden transitions in such a way that perturbation-induced transitions can be used in conjunction with normally allowed transitions to determine the sum of the internal rotation splitting fro two rotational levels differing in K by three units.en_US
