Abstract:

Symmetry of the vibrational-rotational operator of the kinetic energy for pentatomic molecules with three and more identical atoms in the internal nonorthogonal coordinates is considered. The use of nonorthogonal coordinates can significantly simplify simultaneous description of several isotopic modifications of the same molecule.
