Robert W. Field

Robert Field was born June 13, 1944 in Wilmington, Delaware, the first of two children of Kay and Edmund Field. He attended Amherst College where he majored in Chemistry (A. B. Magna cum laude, 1965, Doctor of Science honoris causas 1997). He obtained his graduate education at Harvard University where, supervised by William A. Klemperer, he gained his initial experience with multiple resonance spectroscopies and spectroscopic perturbations (Ph. D. and M. A., 1972). As a postdoc with Professors H.P. Broida and D.O. Harris at UCSB (1971-1974), he performed the first microwave-optical and optical-optical double resonance studies of diatomic molecules using tunable lasers and showed that spectroscopic perturbations can provide global insights into the electronic structure of the alkaline earth monoxides.

Upon joining the MIT Chemistry faculty in 1974 (Assistant Professor 1974-1978, Associate Professor 1978-1982, Professor 1982-1999, Haslam and Dewey Professor of Chemistry 1999-present) he continued to develop new laser spectroscopic techniques including cw optically pumped molecular electronic lasers, modulated gain spectroscopy, and Stimulated Emission Pumping (SEP). His interest in spectroscopic perturbations led him to show that molecular electronic structure and dynamics can often be represented by a simple electrostatic perturbation of free-atomic-ion structures (ligand field theory). While collaborating with Professors James L. Kinsey and Robert J. Silbey, he applied SEP to the study of highly excited vibrational levels of polyatomic molecules and obtained the first experimental evidence for quantum manifestations of classical chaos in an isolated molecule. In collaboration with Professor Anthony Merer, a systematic study of the vibration-rotation structure of S1 acetylene has yielded information about the cis-bent conformer, the shape of the barrier to trans-cis isomerization, and the mechanisms for rotation-vibration state-specific predissociation. A vibrational frequency-dip is shown to be the unique signature of an isomerization transition state. The combination of Chirped Pulse millimeter-Wave spectroscopy with a buffer gas cooled ablation source has yielded a million-fold increase in the “spectral velocity” for an “all spectra and all dynamics” characterization of molecular Rydberg states.

He was elected a Fellow of the American Physical Society (1981), American Academy of Arts and Sciences (1998), the American Association for the Advancement of Science (2002), the Optical Society of America (1994) and the Royal Society of Chemistry (2009). He has been awarded the Herbert P. Broida Prize in 1980, the Earle K. Plyler Prize in 1988, the Ellis Lippincott Award in 1990, the William F. Meggers Award in 1996, the Bomem-Michelson Award in 2006, and the Arthur L. Schawlow Prize in Laser Science in 2009. The 1990 Nobel Laureate Signature Award of the American Chemical Society cites Dr. Yongqin Chen and his co-preceptors (Professors Field and Kinsey) for SEP studies of acetylene. He received the W. F. Meggers Award in Spectroscopy, Optical Society of America, 1996; and an honoris causas Doctor of Science from Amherst College, 1997. He was elected a Fellow of the American Academy of Arts and Sciences, 1998, and the American Association for the Advancement of Science (AAAS) 2002. In 1999 he became the Haslam and Dewey Professor of Chemistry at MIT. Additionally, he received the Bomem-Michelson Award of the Coblentz Society, 2006, the Arthur L. Schawlow Prize in Laser Science from the American Physical Society, and became a Fellow, Royal Society of Chemistry, all in 2009.

His current research interests include: the development of advanced pattern recognition techniques to extract dynamical information (isomerization, intramolecular proton transfer, energy flow, and fluxional behavior) from highly excited vibrational spectra of polyatomic molecules; spectroscopic characterization of triplet states of small polyatomic molecules, especially the doorway-mediated mechanism of Intersystem Crossing; and the mechanisms of energy exchange between electronic and nuclear degrees of freedom, through the spectroscopic study of core-nonpenetrating Rydberg states of diatomic molecules. Robert Field has co-authored three monographs: Perturbations in the Spectra of Diatomic Molecules (1986), The Spectra and Dynamics of Diatomic Molecules (2004), and The Spectra and Dynamics of Small Molecules (2015); he also has co-edited monographs entitled Molecular Dynamics and Spectroscopy by Stimulated Emission Pumping (1995) and Nonlinear Spectroscopy for Molecular Structure Determination (1998).
