Professor Miller received his B.A. degree in Chemistry at the University of Kansas in 1965, and his Ph.D. degree in Chemistry at Cambridge University in 1968. He worked as a Distinguished Member of the Technical Staff at Bell Telephone Laboratories from 1968 to 1984. He joined the Ohio State University in 1984 as the state of Ohio's first Eminent Scholar. In 1992 he became the chairman of the OSU International Symposium on Molecular Spectroscopy. Professor Miller has received numerous research awards including the William F. Meggars Award (Optical Society of America - 1993), the Bomem-Michaelson Award (Coblentz Society - 1995), the Bourke Medal (Royal Society of Chemistry - 1998), the Broida Prize (American Physical Society- 1999), the Plyler Prize (American Physical Society - 2009), and the Morley Prize (Cleveland Society, American Chemical Society - 2009). Professor Miller is editor-in-chief of the Journal of Molecular Spectroscopy. He has served or serves on the following journal editorial boards: Journal of Chemical Physics; Review of Scientific Instruments; Journal of Physical Chemistry; Journal of the Optical Society of America; Chemtracts; Contributing Editor; Annual Reviews of Physical Chemistry; Journal of Molecular Spectroscopy; Laser Chemistry; Journal of Molecular Structure; and Chemical Physics Letters. Professor Miller is a Fellow of the Optical Society of America, American Physical Society, American Chemical Society, and the American Association for Advancement of Science.
Our research centers upon the spectroscopic detection and characterization of short-lived molecular species. Particular targets include reactive chemical intermediates that play critical roles in a variety of processes of intense interest to our society and economy, examples of which include combustion, atmospheric chemistry, and plasma processing of electronic devices. A variety of spectroscopic techniques are available in our lab to observe and characterize reactive species. These techniques include laser induced fluorescence spectroscopy, resonantly enhanced multi- photonionization spectroscopy, cavity ring down spectroscopy, zero electron kinetic energy spectroscopy, and sub millimeter wave spectroscopy. Often gas phase molecules are cooled to near absolute zero by rapid expansion in a supersonic free jet, thereby sharply reducing spectral congestion, and allowing the detailed interpretation of spectra of moderately large molecules. Considerable effort is being made to coordinate experimental and computational investigations. Computational work includes the extensive use of ab initio calculations to narrow the search for new spectra. New approaches are being developed to use ab initio data to interpret observed spectra and in turn use these to benchmark the calculations. Efforts are also being made to apply artificial intelligence techniques to the analysis of spectra. A number of molecular systems are presently being studied, including alkoxy and alkyl peroxy free radicals, both of which are key intermediates in the oxidation of hydrocarbons, whether in our atmosphere or combustion environments. Detailed spectroscopic characterization of aromatic radicals like cyclopentadienyl, small organometallic radicals, and their cations, are being carried out to determine their properties, like Jahn-Teller distortions, and compare them with the best ab initio predictions.More details of the research are available at the group website as well as a complete list of publications.
