Optical Processes in Xenon: Multiphoton Ionization and Ultraviolet Photodissociation of the Dimer Ion
The coefficient for two-photon ionization of xenon at 193 nm has been measured using a microwave absorption scheme which determines peak electron densities. The electron-neutral collision frequency, (nu)(,m), has been obtained using a microwave bridge and the result is consistent with 0.7 eV …

Pseudo-Molecular Ion Formation by Aromatic Acids in Negative Ionization Mode Electrospray Ionization Mass Spectrometry
Pseudo-molecular ion formation is an artifact common to most analyses performed by electrospray ionization mass spectrometry. These species are non-covalent complexes formed between an analyte of interest and any other components (such as mobile phase, additives, and impurities) present in the …

Excitation Spectroscopy of Krypton Molecular Rydberg States
An excitation spectrum of the Kr(,2) ('3)(SIGMA)(,u)('+)(1(,u),O(,u)('-)) excimer has been obtained for 335 (LESSTHEQ) (lamda) (LESSTHEQ) 445 nm and 480 (LESSTHEQ) (lamda) (LESSTHEQ) 545 nm, and Rydberg series of krypton dimers have been observed. The most pronounced peaks in the spectrum have been …

Structures and Reactivities of Ionized and Metal Cation-Containing Acetylene Clusters
In this dissertation, the ion mobility technique is used to determine the structures of small acetylene cluster ions, (C2H2)1-3+, mass-selected from the largest ever reported ionized acetylene clusters. The technique is also used to characterize the reaction of acetylene clusters with water in an …
