چکیده
Measured single-photon zero-kinetic-energy pulsed field ionization ~ZEKE-PFI! photoelectron spectra of the sodium–water complex are presented and compared with the results of rotationally resolved ab initio calculations. The very nonatomiclike behavior of the photoionization of this Na~H2O! complex is essential in accounting for several significant features in these spectra. Agreement between the calculated and measured photoelectron spectra is encouraging. Furthermore, these results suggest that combined experimental and theoretical studies of ZEKE-PFI spectra can be very useful in elucidating the molecular structure and intermolecular force fields of small clusters. © 1998 American Institute of Physics. @S0021-9606~98!01112-X#

Selective field ionization of high Rydberg states: Application to zero-kinetic-energy photoelectron spectroscopy
Sequences of pulsed electric fields have been designed and tested that enable a higher selectivity in the pulsed field ionization of high Rydberg states (n>100) than has so far been possible. The enhanced selectivity originates from the permutation of the parabolic quantum numbers n1 and n2 that is induced by a sufficiently rapid inversion of the electric field polarity during a pulse sequence....

ZEKE - PFI spectroscopy of 1 : 1 complexes of sodium with water and ammonia
ZEKE-PFI (zero kinetic energy pulsed field ionization) photoelectron spectra of the Na(H 20), Na(D20), Na(NH 3), and Na(ND3) complexes are reported. Spectra of all four complexes were obtained by single-photon ionization, and, for the Na(NH 3) and Na(ND3) complexes, by two-color (I+ I') photoionization as well, with the A E state serving as the intermediate resonance. Improved values for the io...
متن کاملZero kinetic energy-pulsed field ionization and resonance enhanced multiphoton ionization photoelectron spectroscopy: Ionization dynamics of Rydberg states in HBr
The results of rotationally resolved resonance enhanced multiphoton ionization photoelectron spectroscopy and zero kinetic energy-pulsed field ionization studies on HBr via various rotational levels of the F D2 and f D2 Rydberg states are reported. These studies lead to an accurate determination of the lowest ionization threshold as 94 098.961 cm. Observed rotational and spin–orbit branching ra...
