Algebraic Model of an Oblate Top,In particular, in spectroscopic studies algebraic methods are very useful to study the symmetries and selection rules, to classify the basis states, and to calculate matrix elements. An exactly solvable model that is of special interest is the symmetric top. As an example, we mention a study by Bohm

Multichannel Dynamic Symmetry,he group, i.e. it can depend on the generators only through the Casimir invariants of the group. If both the potential and the total energy is invariant, the symmetry is called geometric, contrary to the dynamic symmetry which leaves invariant only the total energy [1]. Well-known examples are the .
