Abstract
In the vibration-rotation spectrum of a nonrigid molecule, the degener acy that is clue to several independent energetically equivalent equil ibrium configurations related by exchange transitions ir described usi ng the concept of configurational spin. For the CH3OH molecule with th ree independent configurations related by exchange transitions occurri ng by internal rotation, the algebraic and symmetric properties of thi s spin are analyzed, and effective operators of physical quantities ar e qualitatively constructed based on exchange degeneracy.
