Neglecting centrifugal distortion, the rotational term values for a spherical rotor in an A j vibrational state are [Pg.180]

Although, as in linear and symmetric rotor molecules, the term values are slightly modified by Coriolis forces in a degenerate (T2) state, the rotational selection rules [Pg.180]

For a spherical rotor belonging to the octahedral Of, point group, Table A.43 in Appendix A, in conjunction with the vibrational selection rules of Equation (6.56), show that the only allowed transitions are [Pg.181]

Such bands also obey the rotational selection rules in Equation (6.82) and appear similar to a U-I band of a linear molecule. [Pg.181]
