报告人简介：
Professor Miller received his undergraduate degree from the University of Kansas and his Ph.D. from Cambridge University, where he was a Marshall Scholar. Then he went to Bell Laboratories where he became a Distinguished Member of Technical Staff. Thereafter he became the first Ohio Eminent Scholar Professor and Ohio Eminent Scholar Professor Emeritus at The Ohio State University. He is presently an Academy Professor of OSU. His research centers around the spectroscopic identification, characterization and monitoring of reactive chemical intermediates. He has developed numerous spectroscopic techniques spanning frequencies from the microwave to the ultraviolet and published more than 350 scientific publications.
报告摘要：
Few things affect your quality of life more than the air you breathe and the temperature of your immediate environment. Since more than 80% of the energy used in the industrialized world today is still derived from fossil fuels, these two quantities are not unrelated. Most organic molecules injected into the troposphere are degraded via oxidative processes involving free radical intermediates, and many of these intermediates are the same as the ones involved in the combustion of fossil fuels. Modern spectroscopic techniques like LIF and CRDS allow the detection, monitoring, and characterization of chemical intermediates involved in both atmospheric and combustion-related oxidation of organic molecules. Relevant species that we have studied include the alkoxy (RO) and peroxy (RO2) families (R=CnH2n+1) of radicals as well as the nitrate radical NO3. Specifically we will describe results from LIF experiments on the near-UV electronic spectra of CH3O, C2H5O, and i-C3H7O and their analysis. Related CRDS experiments and analyses of the Ã-X̃ electronic transition in the near-IR of RO2 radicals will be discussed. Time permitting, a brief overview of the near-IR electronic spectrum of NO3 will be presented.
