    A photodissociation study of HgI2 (1992)

    Notes: The photodissociation of jet-cooled HgI2 has been studied in the 244–323 nm region using a tunable ultraviolet (UV) laser. Dispersed emission, action, and multiphoton ionization spectra have been recorded. A vibrational analysis of the action spectra near 305 nm shows that the production of excited Hg atoms from HgI2 UV photodissociation proceeds through a HgI ground-state intermediate. Near 248 nm the results are less conclusive. Possible reasons for a wavelength-dependent kinetic mechanism are discussed.

    Notes: Two-photon resonant, three-photon ionization spectra of jet cooled Xe2, in the region of the Xe* 6p states between 70 000 and 80 000 cm−1, are reported. A new progression, near Xe* 6p[3/2]2, has been analyzed which is both vibrationally and isotopically resolved. Unambiguous assignment of upper state vibrational quantum numbers has resulted in precise molecular constants for the excited state. The transition has been assigned to 1g←0+g using ab initio potential curves. Implications concerning the often used ΔΩ=0 "propensity rule'' are discussed.

    Vacuum ultraviolet laser spectra of ICl (1989)

    Notes: Vacuum ultraviolet fluorescence excitation spectra of jet cooled ICl have been recorded between 158 and 166 nm using a VUV "laser'' generated by four-wave sum-mixing in Mg vapor. An unambiguous vibrational analysis of the spectra has shown that transitions from v‘=0 of the ground state probe high vibrational levels of the first tier EO+ ion-pair state between v'=245 and 360. Molecular constants obtained from both Dunham and near dissociation expansions are presented. Strong intensity modulation of the spectra was observed. Possible reasons for this effect are discussed.

    Mass-resolved two-photon spectra of ArXe in the region of Xe*(6p) (1996)

    Notes: (2+1) resonantly enhanced multiphoton ionization (REMPI) spectra of ArXe have been recorded between ≈78 000 and 80 110.0 cm−1. Single isotopomer data was obtained using a time-of-flight (TOF) mass spectrometer. Vibrational analyses for several transitions involving ArXe excited states that dissociate to Ar(1S0)+Xe*(6p) are presented, in some instances, for the first time. In addition to vibrational numbering and constants, excited state symmetries were deduced from separate REMPI/TOF spectra recorded with linearly and circularly polarized light, while excited state bond lengths were derived from Franck–Condon factor calculations. Some of the excited states were found to have potential humps and/or unusual vibrational band intensity distributions. Where possible, the nature of the perturbations is discussed. © 1996 American Institute of Physics.

    Notes: Resonantly enhanced multiphoton ionization (REMPI) spectra of jet-cooled Xe2 are presented, covering the spectral region between ≈74 627 and 80 849 cm−1. Dimer ions produced by (2+1) REMPI excitation were mass selected in a linear time-of-flight (TOF) mass spectrometer. The vibrational and isotopic structure of several band systems dissociating to Xe* 5p56p and 5p55d asymptotes have been analyzed, many unambiguously for the first time, and molecular constants derived. Equilibrium bond lengths were estimated from Franck–Condon calculations. Insight into excited state predissociation was also obtained by recording atomic TOF excitation spectra. © 1994 American Institute of Physics.

    Notes: Single isotopomer (2+1) resonantly enhanced multiphoton ionization (REMPI) spectra of jet-cooled XeKr have been recorded using time-of-flight (TOF) mass detection. Vibrational analyses for several transitions involving excited states that dissociate to Kr(1S0)+Xe* (6p,5d) between 77 560 and 80 150 cm−1 are reported for the first time. Equilibrium bond lengths were established by Franck–Condon calculations, while excited state symmetries were inferred from excitation spectra recorded using circularly polarized light. A local vibrational perturbation evident in the dominant band system dissociating to Kr(1S0)+Xe*5p56p[5/2]2 has also been analyzed. The identity of the perturbing state is proposed, based in part, on predissociation spectra obtained by monitoring atomic fragments in TOF detection. © 1995 American Institute of Physics.

    Vacuum ultraviolet laser/time-of-flight mass spectroscopy: Ion-pair spectra of 79Br35Cl (1994)
    College Park, Md. : American Institute of Physics (AIP)

    Notes: A newly built vacuum ultraviolet (VUV) laser/time-of-flight mass spectrometer is described, which has been used to record the first vibrationally and rotationally resolved spectra of the E0+ ion-pair state ←X0+ ground state transition of jet-cooled bromine monochloride BrCl, near 145 nm. The mass resolution of the instrument (m/Δm≈1000) was sufficient to obtain single isotopomer data. Preliminary results for 79Br35Cl are reported. Like other interhalogens, BrCl vibronic band intensities vary widely in the VUV, presumably as a result of excited state perturbations. This scenario has been corroborated by the observation of an irregularly spaced vibrational progression, and the irregular behavior of the excited state rotational constants as a function of v'.

    Analysis of the mass-resolved two-photon spectra of jet-cooled ArKr near Kr*(5p) and Ar*(4s) (1996)

    Notes: New (2+1) resonantly enhanced multiphoton ionization (REMPI) spectra of ArKr in the region of Kr*(5p) and Ar*(4s) between ≈92378.8 and 94250.7 cm−1 are presented. A time-of-flight (TOF) mass spectrometer was used to obtain single isotopomer data. Four band systems, two previously observed by Dehmer and Pratt [J. Chem. Phys. 88, 4139 (1988)], and two new ones, have been vibrationally analyzed. Excited state bond lengths have been found from Franck–Condon factor calculations while electronic symmetries were assigned from REMPI spectra recorded with circularly polarized light. Our excited state symmetry assignments differ from those recently proposed by Heck et al. [J. Phys. Chem. 99, 17700 (1995)]. The unusual vibrational band intensity distributions observed for some of the electronic systems are rationalized qualitatively in terms of interstate avoided crossings. © 1996 American Institute of Physics.
