Laurence A. Nafie, Syracuse University, received the 2013 Pittsburgh Spectroscopy Award presented by the Spectroscopy Society of Pittsburgh (SSP). The SSP Award, established in 1957, honors an individual who has made outstanding contributions in the field of spectroscopy.
This mini-virtual event comprises a brief 5 minute video which shows Professor Nafie being presented with his Award at Pittcon on Tuesday, March 19. This is followed by a live 40 minute presentation (PowerPoint and live video-feed) of Prof. Nafie giving the presentation that he gave at his Award Ceremony. On-demand users will still have the opportunity to submit questions to Professor Nafie who will reply by email.
Both IR and Raman forms of vibrational optical activity (VOA) were discovered experimentally nearly 40 years ago. The IR form is vibrational circular dichroism (VCD) and the Raman form is Raman optical activity (ROA). For the first 20 years of VOA, VCD and ROA passed through a period of gradual growth spearheaded by a few academic laboratories. Then in mid-1990s two developments occurred for VCD, followed a few years later for ROA. These were the commercial availability of instrumentation for measurements and software for calculations. The comparison of measured and calculated VOA yields new insights into the absolute structure and conformation of chiral molecules. In the past 15 to 20 years VOA has undergone a period of rapid growth and maturation. Hundreds of scientists in both academic laboratories and pharmaceutical companies now use VOA on a regular basis to explore its depth of molecular information and to solve stereochemistry problems of practical importance. Academic labs use VOA primarily to determine the conformation of biological molecules and to explore the effects of solvents and anharmonicity using computed VOA. Pharmaceutical companies use VOA to determine the absolute configuration of new chiral drug substances and to probe the higher order structure of biopharmaceutical molecules. In this presentation, the extent of the routine use of VCD to determine absolute configuration of pharmaceutical and natural product molecules will be described as well as the use of VCD to reveal the underlying supramolecular chiral structure of amyloid fibrils of interest in relation to the incidence of neurological diseases.

Syracuse University, NY, USA
Laurence A. Nafie received his Ph.D. from the University of Oregon in 1973 and was then a postdoctoral associate at the University of Southern California, where he confirmed the discovery of infrared vibrational circular dichroism (VCD). In 1975 he joined the Chemistry faculty at Syracuse University and pursued a research program in VCD and Raman optical activity (ROA) until his retirement in 2010. He has over 290 publications and several patents. Currently he is Emeritus Distinguished Professor at Syracuse University and Editor-in-Chief of the Journal of Raman Spectroscopy. In 2011 he published a comprehensive book on VOA entitled Vibrational Optical Activity: Principles and Applications.
