Abstract
In the vibration-rotation spectrum of a nonrigid molecule, the degeneracy that is due to several independent energetically equivalent equilibrium configurations related by exchange transitions is described using the concept of configurational spin. For the CH3OH molecule with three independent configurations related by exchange transitions occurring by internal rotation, the algebraic and symmetric properties of this spin are analyzed, and effective operators of physical quantities are qualitatively constructed based on exchange degeneracy.
