Low-lying gerade electronically excited states of the Xe dimer, viz., 1 g and 0 g ϩ , with a Xe 1 S 0 ϩXe* 6s[3/2] 1 dissociation limit have been investigated using two-photon resonance enhanced multiphoton ionization techniques. High resolution is achieved by using this method in combination with a supersonic expansion. Moreover, the mass-resolved ion detection used in the present experiments has led to the observation of both vibrationally well-resolved spectra and continuous features, allowing the bound and dissociative parts of the excited states to be investigated separately. All spectra have been measured under both linearly and circularly polarized excitation conditions, enabling an unambiguous assignment of the signals. On the basis of FranckCondon calculations information on the potential energy curves of the bound and dissociative parts of the excited states has been obtained.

Evidence for fast intramolecular vibrational relaxation within the 1 E 1u state ~i~eti,: energy r~solv.ed. electron detection is used to study resonance enhanced multiphoton 10mzatIOn and dissociation of molecular chlorine via the 2 III g Rydberg state. In the twop,hoton ener~ regio? bet~e~n 63 ~ and 73 600 cm -I, a long vibrational progression up to v = 1.5 associated with this mtermedlate gerade Rydberg state is observed. The regularity and magmtude of the vibrational spacing indicate that the 2 IIIg state, converging to the ionic ground state, has virtually unperturbed Rydberg character. However, the molecular signals in the photoelectron spectra show strong deviations from Franck-Condon behavior. In addition intense electron signals arising from one-photon ionization of excited chlorine atoms are ' observed. An interpretation in terms of a competition between electronic autoionization and dissociation from core-excited molecular Rydberg states situated above the lowest ionization energy is ~resent~d. Some of t?e excited atomic states observed are indicative for Rydberg-Rydberg mteracttons at large mtemuclear distances in the dissociation channel.6042

Download date: 11 May 2018A (34-I) resonance enhanced multiphoton ionization study of the C 'X+ and E 'II states of CO: Polarization dependence used to probe electronic excitation routes and electronic character The three-photon excitations of the C IX+ and E 'Il states have been investigated with resonance enhanced multiphoton ionization spectroscopy as a function of the polarization of the excitation light. From the observed polarization dependence the contributions of the various excitation routes have been determined, and the electronic character of these states has been analyzed. The results indicate that the v' =0 and 1 vibrational levels of the E 'II state have slightly different electronic characters.
