β¦ Synopsis
Using sub-Doppler double resonance excitation individual high-n Rydberg states were excited in a polyatomic molecule. Even for a selected JK intermediate rovibrational state in benzene, C6D6, several Rydberg series are observed converging to different limits. The pulsed field ionization signal has a decay time that is longer than expected from measured lifetimes of low Rydberg states of benzene and ascribed to/-mixing in the residual electric stray field.

Photoionization spectra of pure CHII and of CH,I doped into varying densities of Ar (up to 10.5 x 10" cm-') are reported. The photoionization spectrum of pure CHJ closely reproduces the absorption spectrum of the autoionizing nd' and ns' Rydberg states converging to the 'E,,\* ionization limit. More
