The vibrational kinetic energy operator is constructed for the AB4-type molecules in different orthogonal nonsymmetrized and symmetrized coordinates. Different forms of the vibrational kinetic energy operator are analyzed from the viewpoint of convenience of its use in solving the vibrational problem.
