✦ Synopsis

This work presents the three-photon resonant, one-photon ( 3 + 1) ionization spectrum of chlorine in the region of 73 170-79360 cm-' above the neutral ground state. In contrast to one-photon experiments, an intense double-peaked band progression attributed to "Cl2 and "Cl "Cl is observed in this energy region and assigned to a 'Z,( v'= 0-7)+X 'Xi (u"= 0) Rydberg excitation. The molecular constants of the 'X, Rydberg well as determined from the vibrational progression are T,= 74013 (5) cm-', 0.=628(3) cm-' and 0&~=4.4(6) cm-'.

Two-and three-photon resonance-enhanced multiphoton ionization spectra of the 3d Rydberg states of CS2 in the 154-160 nm region are reported. Noting that the selection rules for multiphoton transitions are quite different from those of one-photon transitions, the electronic origin of the 3dA8 Rydber

Using the single-photon time correlation sxtetf'od, we have determined the lifetime of the Sz (B 3X3) state from the decay rate of the fluorescence at 370 nm. A lifetime of 45.0 t 0.6 n5 was measured, and the cross section for fluorescence quenching by Sz as found to be 8J -3 t 4.7 A\*. A slight dep
