Book excerpt: Rapid advances in laser and detector technologies are making it possible to investigate molecular photophysics and photochemistry in powerful new ways. For example, resonantly enhanced multiphoton ionization (REMPI) measurements, in which the total (or the mass selected) ion current is monitored as a function of laser wavelength, have yielded extensive and often novel information on the spectroscopy of the resonant intermediate states. With the addition of photoelectron spectrometry (PES) to analyze the kinetic energy of the ejected electrons, it is possible to determine the branching ratios into different electronic, vibrational, and rotational levels of the product ion and to focus directly on both the dynamics of the multiphoton ionization process and the photoionization of excited state species. In the present paper, we report several REMPI/PES studies of H2 and N2. The results reflect both the spectroscopy and the dynamics of photoionization of excited molecular states and are discussed in terms of the selection rules for photoionization and the relative probabilities of photoionization from Rydberg and valence states. In some cases, in accordance with the Franck-Condon principle, the results demonstrate that resonant multiphoton ionization through Rydberg states may be a powerful technique for the production of electronic, vibrational, and rotational state selected ions. However, in other cases, systematic departures from Franck-Condon behavior are observed, which reflect the more subtle dynamics of excited state photoionization.

This book was released on 1984 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report summarizes research on resonantly enhanced multiphoton absorption dissociation, and ionization processes in atoms and molecules. Multiphoton processes are studied using from one to three independently tunable visible and/or UV laser beams in order to establish both the underlying physics and the high degree of selectivity of multiphoton processes. Measurements are made to probe both the formation of excited molecular states and the subsequent behavior of excited states either in the presence or in the abscence of further intense laser radiation. Detection methods include laser-induced fluorescence, ion mass analysis, and electron energy analysis. During the current reporting period, we have studied resonant multiphoton ionization processes for the molecules N2, CO, O2, NO, NeXe, ArXe, KrXe, and Xe2 and for the atoms C, I, and S using both mass spectrometry and photoelectron spectroscopy to analyze the products of the ionizations. In addition, we are developing three new instruments that will provide significantly enhanced resolution, collection efficiency, and versatility in both the ion mass and the electron kinetic energy detection channels. Keywords include: double resonance spectroscopy, electron spectroscopy, molecular beams, rydberg states; photoelectron angular, distributions. (Author).

Book excerpt: Resonant multiphoton ionization (MPI) of nitrogen has been studied using photoelectron spectroscopy in the short-pulse regime. Both Rydberg and valence states are identified as intermediate resonances in the photoionization process, although the valence states are seen only at low intensity. It is shown that the vibrational structure of the Rydberg states acting as intermediate resonances cancels out in the photoelectron spectrum, leading to sharp atomic-like spectra, even at high intensities. Finally, the ionization of the 3 sigma sub g 1 pi sub u and 2 sigma sub u electrons are clearly distinguished.

This book was released on 2001 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The overall objective of this work is to carry out quantitative theoretical studies of these laser-driven ionization processes in molecules so as to provide both a robust description of key spectral features of interest in applications and related experiments and needed insight into these spectra. A major focus of this effort is combined theoretical-experimental studies of molecular ion spectra which are being widely studied by the zero-kinetic-energy (ZEKE) technique. This ZEKE technique, which is base3d on pulsed-field ionization (PFI) of very high Rydberg states, makes it possible to obtain ion distributions with sub-wavenumber resolution and is clearly opening up entirely new vistas in studies of molecular ionization. Some highlights of the progress include: (1) The author has extended the theoretical formulation and computational procedures used in these studies of molecular ionization spectra to general polyatomic systems; (2) He has completed combined theoretical-experimental studies of the molecular ion distributions for photoionization of H[sub 2]S, H[sub 2]CO, and CH[sub 3] by coherent VUV radiation; (3) He has carried out the first calculations of the molecular ion rotational distributions for electronically excited states of NO[sup+] (a[sup 3][Sigma][sup+]) and CO[sup+] (A[sup 2][Pi]); (4) he has also completed calculations of the ion rotational distributions for laser ionization of the small prototypical radicals OH, NH, and CH; and (5) Extensions of the studies of molecular photoionization processes of interest here to large polyatomic molecules are computationally quite demanding. These computational demands arise primarily from complexities associated with the quantum mechanical equations which must be solved to obtain the photoelectron wavefunctions required in these studies. To meet these computational needs the author is currently developing strategies for carrying out these calculations on massively parallel computers such as the Intel Paragon and Cray T3D.
