Studies of the spectroscopy and dynamics of transient energetic species by anion photodetachment and cation recombination processes are reported. Experimental efforts focused on sulfur, nitrogen and oxygen clusters. The research included the first report of a 5-fold coincidence measurement in a study of O bar-8 -> O2+O2+O2+O2+e.

Free radicals, weakly bound van der Waals complexes, and metal and semiconductor clusters are characterized by photodetachment of the corresponding negative ions using slow electron velocity-map imaging (SEVI), a recently developed, high-resolution (2-3 cm-1) variant of negative ion photoelectron spectroscopy. The SEVI spectrum of a negative ion yields the electron affinity of the neutral, term values for excited states accessible via one-photon detachment, and accurate vibrational frequencies for the ground and accessible excited states. The combination of high energy resolution and the simultaneous measurement of photoelectron angular distributions provides a sensitive probe of adiabatic potential energy surfaces and vibronic coupling in neutral species formed by photodetachment. The SEVI experiments are complemented by infrared studies of size-selected negative ions and clusters using the free electron laser FELIX.

This research concerns the study of the spectroscopy and excited state dynamics of a number of transient molecules containing either sulfur or oxygen. The identification and study of sulfur species which are analogs of important oxygen-containing combustion intermediates is important to our understanding of reactive intermediates. The oxygen-containing species chosen for study are new systems whose electronic spectra have not previously been identified. The major experimental technique used in this work was pyrolysis jet spectroscopy. Since many of the species have not been previously studied by laser techniques, much effort was devoted to determining methods for producing and observing them. We have been very successful in a number of cases and have developed some further experimental techniques.

This research is carried out as part of the Gas-Phase Molecular Dynamics program in the Chemistry Department at Brookhaven National Laboratory. Chemical intermediates in the elementary gas-phase reactions involved in combustion chemistry are investigated by high resolution spectroscopic tools. Production, reaction, and energy transfer processes are investigated by transient, double resonance, polarization and saturation spectroscopies, with an emphasis on technique development and connection with theory, as well as specific molecular properties.

Work was done on sub-Doppler spectroscopy of thioformaldehyde, electronic spectrum of FS2 radical, FTIR spectra of the transient molecule formyl chloride (HCOCl and DCOCl), and high-resolution FTIR spectra of the?9 (CH2 wag) and?5 (CSO symm. stretch) bands of sulfine (H2CSO), a transient species formed in pyrolysis of dimethyl sulfoxide and oxidation of thioformaldehyde.

This book is a stop-gap contribution to the science and technology of carbon plasmas and carbon vapors. It strives to cover two strongly related fields: the molecular quantum theory of carbon plasmas and carbon nanostructures; and the molecular and atomic spectroscopy of such plasmas and vapors. These two fields of research are strongly intertwined and thus reinforce one another.Even though the use of carbon nanostructures is increasing by the day and their practical uses are emerging, there is no modern review on carbon plasmas, especially from molecular theoretical and spectroscopic viewpoints. The importance of the present book is therefore great from both educational and practical aspects. This review might be the first step towards bringing such textbooks into existence for university education. Similarly, for applied and engineering works in carbon nanostructures, the book provides a theoretical salient point for technologists in the field.
