Infrared spectroscopy is the measurement of the interaction of infrared radiation with matter by absorption, emission, or reflection. It is used to study and identify chemical substances or functional groups in solid, liquid, or gaseous forms. It can be used to characterize new materials or identify and verify known and unknown samples. The method or technique of infrared spectroscopy is conducted with an instrument called an infrared spectrometer which produces an infrared spectrum. An IR spectrum can be visualized in a graph of infrared light absorbance on the vertical axis vs. frequency, wavenumber or wavelength on the horizontal axis. Typical units of wavenumber used in IR spectra are reciprocal centimeters, with the symbol cm−1. Units of IR wavelength are commonly given in micrometers, symbol μm, which are related to the wavenumber in a reciprocal way. A common laboratory instrument that uses this technique is a Fourier transform infrared (FTIR) spectrometer. Two-dimensional IR is also possible as discussed below.
Spectroscopy is the field of study that measures and interprets electromagnetic spectra. In narrower contexts, spectroscopy is the precise study of color as generalized from visible light to all bands of the electromagnetic spectrum.
William Weber Coblentz was an American physicist notable for his contributions to infrared radiometry and spectroscopy.
Kevin K. Lehmann is an American chemist and spectroscopist at the University of Virginia, best known for his work in the area of intramolecular and collisional dynamics, and for his advances in the method of cavity ring down spectroscopy (CRDS).
The Society for Applied Spectroscopy (SAS) is an organization promoting research and education in the fields of spectroscopy, optics, and analytical chemistry. Founded in 1958, it is currently headquartered in Frederick, MD. In 2006 it had about 2,000 members worldwide.
Richard C. Lord (1910–1989) was an American chemist best known for his work in the field of spectroscopy.
The Williams–Wright Award is an award that honors extraordinary or outstanding work in spectroscopic measurements while working in an industrial setting. The award has been given by the Coblentz Society annually since 1978 with the Awardee being selected by a committee of leading spectroscopists. The Award citations reads, "The Coblentz Society proudly presents the Williams–Wright Award to --- for his/her outstanding contributions to the Field of Industrial Spectroscopy."
William A. Klemperer (October 6, 1927 – November 5, 2017) was an American chemist, chemical physicists and molecular spectroscopists. Klemperer is most widely known for introducing molecular beam methods into chemical physics research, greatly increasing the understanding of nonbonding interactions between atoms and molecules through development of the microwave spectroscopy of van der Waals molecules formed in supersonic expansions, pioneering astrochemistry, including developing the first gas phase chemical models of cold molecular clouds that predicted an abundance of the molecular HCO+ ion that was later confirmed by radio astronomy.
The Federation of Analytical Chemistry and Spectroscopy Societies or FACSS is a scientific society incorporated on June 28, 1972, with the goal of promoting research and education in analytical chemistry. The organization combined the many smaller meetings of the individual societies into an annual meeting that includes all of analytical chemistry. The meetings are intended to provide a forum for scientists to address the development of analytical chemistry, chromatography, and spectroscopy.
Bernhard Schrader was a German professor of Theoretical and Physical Chemistry and teaching until his retirement in 1996 at the University of Essen, where he died. Schrader was an internationally acclaimed pioneer of experimental molecular spectroscopy in Germany, especially of Raman- and Infrared spectroscopy and its routine application in chemical analysis. Amongst his numerous achievements was his historic landmark paper with Bergmann of 1967 about the first successful use of Transmission Raman spectroscopy for chemical analysis of Organic solids, e.g. pharmaceutical powders, which has become routine industry practice since that approach was "rediscovered" in 2006.
Isao Noda is a chemical engineer whose research has focused on polymer science and spectroscopy. He holds ninety patents granted in the United States and the EU, has published over three hundred articles, co-authored three books, and received a number of industry-wide awards and recognition for his contributions to his fields of research.
Geraldine Lee Richmond is an American chemist and physical chemist who is serving as the Under Secretary of Energy for Science in the US Department of Energy. Richmond was confirmed to her DOE role by the United States Senate on November 5, 2021. Richmond is the Presidential Chair in Science and professor of chemistry at the University of Oregon (UO). She conducts fundamental research to understand the chemistry and physics of complex surfaces and interfaces. These understandings are most relevant to energy production, atmospheric chemistry and remediation of the environment. Throughout her career she has worked to increase the number and success of women scientists in the U.S. and in many developing countries in Africa, Asia and South America. Richmond has served as president of the American Association for the Advancement of Science, and she received the 2013 National Medal of Science.
Yukihiro Ozaki is a Japanese scientist. Kwansei Gakuin University, Department of Chemistry, School of Science and Technology, professor emeritus, Fellow.
Heather Cecile Allen is a research chemist, who leads the Allen Group at Ohio State University. Allen's research focuses on interfacial phenomena, particularly those involving water and air. Her work has broad application ranging from medicine to climate change. She also develops nonlinear optical spectroscopy and microscopy instruments for the examination of interfacial surfaces.
Foil Allan Miller was an American chemist and philatelist best known for his work in infrared and Raman spectroscopy. He was head of the spectroscopy division of the Mellon Institute and later professor and head of the spectroscopy laboratory at the University of Pittsburgh. Among other publications, he co-authored the books Course Notes on the Interpretation of Infrared and Raman Spectra (2004) and A Philatelic Ramble Through Chemistry (1998).
Jeanette Grasselli Brown is an American analytical chemist and spectroscopist who is known for her work with Standard Oil of Ohio as an industrial researcher in the field of spectroscopy.
Christy Lynn Haynes is a chemist at the University of Minnesota. She works at the interface of analytical, biological, and nanomaterials chemistry.
Jon Torger Hougen was an American spectroscopist.
Karen Jane Faulds is a Scottish academic and Professor of Analytical Chemistry at the University of Strathclyde. She develops surface-enhanced Raman spectroscopy (SERS) for bioanalysis, and has won several awards for her research, including the Coblentz Society Craver Award.
Mitsuo Tasumi was a Japanese physical chemist known for his vibrational spectroscopic works on synthetic and biological macromolecules. He was Professor Emeritus of the University of Tokyo, and a former president of Saitama University, having trained a number of physical chemists active in academia and industry. Moto-o Tasumi, a zoologist at Kyoto University, was his brother.
