Abstract

The notion of configurational spin is introduced to describe the configurational degeneracy in the vibration-rotation spectrum of a nonrigid molecule, i.e., the degeneracy that is due to the presence of several independent and energetically equivalent equilibrium configurations. The NH3 molecule, which has two such configurations related by inversion, is used to analyze the algebraic and symmetric properties of the spin. The qualitative construction of the operators of the observables on the basis of this spin is discussed.
