Energy levels of an asymmetric top with two internal rotors of C3v symmetry

Format:
J Ka Kc s

Details: Each level is characterized by the usual asymmetric top quantum numbers J, Ka, and Kc, and symmetry number σ. A combination of (σ12) values of upper and lower levels corresponds to a combination of symmetry species Γ1Γ2 of C3v symmetry point group. The correspondence is given in the table →
