Energy positions and assignments of lines observed in the region of the and ionization thresholds. Peak labels refer to Fig. 2.

Generic image for table
Table II.

Energy positions and assignments of peaks observed after excitation around the orbital of methyl chloride. Notations are from Refs. 6 and 7, where the Rydberg levels are treated as extensions of the halogen atomic orbitals. According to these last two references, nomenclature reflecting molecular symmetries and in the group has been retained for some Rydberg states, contrary to assignments presented in Table I.
