Abstract
In this chapter, the model of super-rotation is introduced. In this model, the internal and overall rotation of extremely floppy molecules is treated as indistinguishable and hence both are treated together in a higher-dimensional rotor model. In particular, by releasing the internal rotor axis and its angle, one is led to use a five-dimensional rotor approach. The energy expression of a five-dimensional rotor is discussed and compared to that of traditional internal rotor theories.

The permutation group is \({\varvec{C}}_{3}=\{E,(123),(132)\}\) and has a totally symmetric irreducible representation A and a two-dimensional one, say, E (see p. 578 of [26]).
