Two-Dimensional Correlation Spectroscopy
One-Day Course E09-19: Tuesday, November 17, 2009, 8:30am – 5:00pm
Dr. Isao Noda, Procter & Gamble Company, West Chester, OH
COURSE DESCRIPTION
Two-dimensional (2D) correlation spectroscopy is a relatively new addition to the field of optical spectroscopy. In 2D spectroscopy, a
spectrum is obtained as a function of two independent spectral valuables, such as wavenumbers. Peaks are spread over the second
dimension, thereby simplifying the visualization of complex spectra consisting of many overlapped bands, and thus enhancing spectral
resolution. Relationships among various spectral bands are characterized by the presence or absence of 2D cross peaks. The new correlation formalism provides a unified model-free path to the construction of useful 2D correlation spectra for wide ranges of spectral data, obtained by common electromagnetic probes (e.g., IR, Raman, NIR, UV, visible, fluorescence, x-ray, NMR, and so on) under various experimental conditions. In fact, this technique can also be extended to the analysis of data outside of spectroscopy, such as chromatography and microscopy. In this short course, an overview and detailed tutorial will be provided for this powerful and versatile technique with many application examples, including the study of synthetic polymers, bio-molecules, surfaces, and many other industrially important systems. The course includes the hands-on exercise of actual 2D correlation analysis by using free software.
WHO SHOULD ATTEND
The course is intended for general audience with some basic technical background, including chemists, physicists, biologists, engineers, material scientists, and students at graduate or undergraduate level. Almost anyone who uses spectroscopic techniques in a part of their work will benefit from taking this course. Some basic mathematical tools, such as Fourier transform and correlation analysis, are used as a background, but no in-depth knowledge in mathematics is required.

ABOUT THE INSTRUCTOR
Dr. Isao Noda was born in Tokyo, Japan. He came to the United States in 1969 and was graduated from Columbia University in the City of New York in 1974 with B.S. degree in chemical engineering. He also received his M.S. in bioengineering (1976), as well as M.Phil. (1978) and Ph.D. (1979) in chemical engineering from Columbia. In 1997 he received D.Sc. degree in chemistry from the University of Tokyo. He is currently a Research Fellow of the Procter and Gamble Company in Cincinnati, Ohio. His research interest is in the broad area of polymer science and spectroscopy. He is well known for the development of two-dimensional infrared (2D IR) correlation spectroscopy. He has also been actively involved in the research and development of a novel class of bio-based biodegradable plastics called NodaxTM. He is a recipient of the 1991 William F. Meggers Award from the Society for Applied Spectroscopy and the 2002 Williams-Wright Award from the Coblentz Society. In 2002, he was appointed to the position of Honorary Adjunct Professor of the Department of Biological Science and Biotechnology at Tsinghua University in Beijing, China. He was selected as the 2005 Chemist of the Year by the Cincinnati Section of the American Chemical Society. He received the International Academic Cooperation and Exchange Medal in 2008 from the Chinese Chemical Society and Chinese Optical Society. Dr. Noda is the recipient of the 2009 New York Section of the Society for Applied Spectroscopy Gold Medal Award which will be presented at this year’s EAS.
