✦ Synopsis

The energy spectrum of a superexcited state (the difference between the total photoabsorption and photoionization CIOSS sections) is calculated usiilg ultraviolet photoelectron data for CH4 and oscillator strength data for the isoelectronic atom, NC. From this estimate we have concluded that the superexcited state of CA4 is interpreted in terms of Jahn-Teller distortion of high Rydberg states referring to the ?2 state of CHZ. The inconsistency between the data of the UV optical spectrum and results of other measurements or analyses is pointed out and discussed.
