Arnold C. Ott Lectureship in Chemistry

Dan Neumark

Dr. Daniel Neumark

University of California, Berkeley

Research Interests Physical Chemistry, Molecular Structure and Dynamics

Prof. Neumark and his research group carry out state-of-the-art experiments to probe fundamental problems in chemical physics. The projects in his laboratories encompass (i) reaction dynamics of bimolecular and unimolecular reactions, in which one maps out in detail the potential energy surfaces on which chemistry occurs, (ii) cluster spectroscopy and dynamics, which explore how the properties of matter evolve with size, and (iii) ultrafast x-ray science, where novel femtosecond and attosecond light source initiate and/or probe dynamics in the soft x-ray regime. 

The Arnold C. Ott Lectureship in Chemistry was created and endowed by a generous gift from Dr. Arnold C. Ott and Marion Ott. Dr. Ott received his Ph.D. in 1943 from Michigan State University in Chemistry/Physics/Bacteriology and is a leading chemist and entrepreneur in West Michigan. He is one of the co-founders of Grand Valley State University and served on the GVSU Board of Trustees for 28 years.

Title: Chemical reactions:  what lies under the arrow?

Abstract: The transition state, a transient species intermediate between reactants and products, is a central concept throughout many areas of chemistry, ranging from fundamental reaction dynamics to enzymology and industrial catalysis.  The transition state serves as a "bottleneck" through which reactants must pass through en route to products and thus governs key aspects of chemical reactivity.  However, owing to its transient nature, the transition state has been resistant to conventional methods of spectroscopic analysis.  This talk will focus on the concept of the transition state, its role in chemical reactions, and the techniques developed in our laboratory and elsewhere to characterize it.

Title: Studies of radicals, catalytic intermediates, and transition states by slow electron velocity-map imaging of cryogenically cooled anions (cryo-SEVI)

Abstract: Slow-electron velocity-map imaging of cryogenically cooled anions (cryo-SEVI) is a high resolution variant of anion photoelectron spectroscopy that yields spectra of complex species with resolution as high as 1-2 cm-1. This resolution is achieved by trapping anions in an octopole trap in which buffer-gas cooling brings their temperature down to approximately 10 K. The anions are then extracted from the trap, mass-selected, and photodetached. The resulting photoelectrons are analyzed with velocity-map imaging electron optics set up to selectively collect slow electrons. This technique reveals extensive vibrational structure associated with the neutral species generated by photodetachment, and enables one to investigate species that were previously spectroscopically intractable. Results will be presented for free radicals, bare and complexed metal oxide clusters, and transition state species associated with benchmark unimolecular and bimolecular reactions.
