This book was released on 1997 with total page 17 pages. Available in PDF, EPUB and Kindle. Book excerpt: Resonance Enhanced Multiphoton Ionization (REMPI) utilizes pulsed laser radiation to prepare a molecule in an excited state via absorption of one or more photons and to subsequently ionize that state before it can decay. A remarkable feature of REMPI, and one that is very basic to many of its applications and uses, is that the very narrow bandwidth of the {open_quotes}pump{close_quotes} laser makes it possible to select a specific vibrational and rotational level in the initial state and to prepare the excited state of interest in a single vibrational and rotational level. Thus, by suitable choice of the photon pump transition, it is possible to selectively ionize a species of interest without ionizing any other species that might be present. This feature makes REMPI one of the most powerful tools for ultrasensitive detection of species. With REMPI it is also possible to study the photoionization dynamics of a single rotational level of an excited electronic state. Such state-resolved studies can certainly be expected to provide significant insight into the underlying dynamics of molecular photoionization.

Book excerpt: Resonance Enhanced Multiphoton Ionization (REMPI) utilizes pulsed laser radiation to prepare a molecule in an excited state via absorption of one or more photons and to subsequently ionize that state before it can decay. The overall objective of this effort is to carry out theoretical studies of these REMPI processes in molecules and molecular fragments which are designed to provide a robust analysis and prediction of key spectral features of interest in several experimental studies and applications of this technique. A specific and very important objective of the effort is to predict the vibrational and rotational ion distributions which result from REMPI of representative molecules and to understand the underlying mechanisms that give use to these ion distributions. The author highlights progress made during this period.

This book was released on 1993 with total page 21 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this report, the author will review the progress made in his studies of ion rotational distributions resulting from resonance enhanced multiphoton ionization of excited electronic states and from single-photon ionization of ground electronic states of jet-cooled molecules by coherent VUV and XUV radiation. To do so he will select a few examples from his studies which serve to highlight his progress and to identify the background and significance of the specific spectral features and systems he has chosen to study.

This book was released on 1997 with total page 4 pages. Available in PDF, EPUB and Kindle. Book excerpt: In resonance enhanced multiphoton ionization (REMPI) pulsed laser radiation is utilized to prepare a molecule in an excited state via absorption of one or more photons and to subsequently ionize that level before it decays. A remarkable feature of REMPI is that the very narrow bandwidth of laser radiation makes is possible to select a specific rotational level in the initial (ground) state and to prepare the excited state of interest in a single rotational level. By suitable choice of the excitation step, it is thus possible to selectively ionize a species of interest present in very minor concentrations without ionizing any other species that may be present. This feature makes REMPI a very powerful tool for ultrasensitive detection of trace or transient species.

Available in PDF, EPUB and Kindle. Book excerpt: Specialist Periodical Reports provide systematic and detailed review coverage of progress in the major areas of chemical research. Written by experts in their specialist fields the series creates a unique service for the active research chemist, supplying regular critical in-depth accounts of progress in particular areas of chemistry. For over 80 years the Royal Society of Chemistry and its predecessor, the Chemical Society, have been publishing reports charting developments in chemistry, which originally took the form of Annual Reports. However, by 1967 the whole spectrum of chemistry could no longer be contained within one volume and the series Specialist Periodical Reports was born. The Annual Reports themselves still existed but were divided into two, and subsequently three, volumes covering Inorganic, Organic and Physical Chemistry. For more general coverage of the highlights in chemistry they remain a 'must'. Since that time the SPR series has altered according to the fluctuating degree of activity in various fields of chemistry. Some titles have remained unchanged, while others have altered their emphasis along with their titles; some have been combined under a new name whereas others have had to be discontinued. The current list of Specialist Periodical Reports can be seen on the inside flap of this volume.
