Treating the symmetry operations as transformations in higher dimensional space, it is shown that Wigner’s method can be straightaway extended to study the vibrations of nonrigid molecules exhibiting free or nearly free internal rotations. The molecule B(CH3)3 is illustrated.
Volume 16 Issue 6 June 1981 pp 473-479 Atomic And Molecular Physics
Motivated by Altmann’s definition of symmetry groups of nonrigid molecules, Wigner’s method of obtaining the symmetry coordinates of a molecule is extended to nonrigid molecules with free internal rotations. The molecule BF2 CH3 is exemplified.
Volume 23 Issue 6 December 1984 pp 803-808 Molecular Physics
Exploring the concept of quasisymmetry, a simple and elegant method, for the classification of molecular structures, has been developed. Examples are given. Results are identified with those of Pople.
