Energy levels of an asymmetric top with a single internal rotor of C3v symmetry

Format:
J Ka Kc m F

Details: Each level is characterized by the usual asymmetric top quantum numbers J, Ka, and Kc, and the free rotor quantum number m. When table includes hyperfine levels, standard F = J+I quantum number is added to the labeling. The correspondence between m quantum number in .cat file and the vibrational torsional quantum number vt and symmetry species Γ = A or E of C3v symmetry point group is given in the table →
