Chemistry 3B - Lecture 03: Electronic Spectroscopy Chemistry 3B: Chemical Structure and Reactivity. Spring 2006. Professor Peter Vollhardt. Chemistry 3B represents the second semester of the standard organic chemistry series at UC Berkeley. It covers conjugation, aromatic chemistry, carbonyl compounds, carbohydrates, amines, carboxylic acids, amino acids, peptides, proteins, and nucleic acid chemistry. Ultraviolet spectroscopy and mass spectrometry will be introduced. Organic chemistry is a specific discipline within the subject of chemistry. It is the scientific study of the structure, properties, composition, reactions, and preparation of chemical compounds of carbon and hydrogen, which may contain any number of other elements, such as nitrogen,...

Some Statistical Problems in Spectroscopy and Hyperspectral Imaging Google Tech Talks July 23, 2008 ABSTRACT Every material has a distinctive spectrum. The spectrum of a material tells us about its chemistry. Hyperspectral images produce a spectrum (represented as several hundred numbers) at each pixel in an image. So hyperspectral images enable us to map variations in chemistry. The first hyperspectral scanners, built in the 1980's and 1990's, were designed for airborne applications, primarily for mineral, environmental and military applications. However, in recent years, hyperspectral microscopes and cameras have been developed and are being used for terrestrial applications in areas such as medical diagnosis, burns analysis and skin cancer, biosecurity, pharmaceuticals, forensics and in agribusiness. A significant issue in hyperspectral imaging is that the spectra at many pixels in an image are actually mixtures of the spectra of the pure ingredients. My main focus over a number of years has been on developing fast and sophisticated algorithms and software for "unmixing" these spectra into their pure ingredients, both when the pure ingredients are known and when they are unknown. This has resulted in two software packages: The Spectral Assistant (TSA), which has been incorporated into another CSIRO package, The Spectral Geologist, which itself has been sold to over 100 (mainly exploration and mining) companies around the world; and Iterated Constrained Endmembers (ICE), which has yet to be commercialized. I will give an overview of the algorithms underlying TSA and ICE, and demonstrate their application to some mineral, remotely sensing and biological data sets. Finally, I will discuss some unsolved statistical and computational problems associated with these packages. Speaker: Mark Berman Mark Berman received the B.Sc.(Hons.) degree and University Medal in mathematical statistics from the University of New South Wales in 1974, and the Master of Statistics degree from the same institution in 1976. In 1978, he was awarded the Ph.D. and D.I.C. degrees in mathematical statistics by the Imperial College of Science and Technology, London. He was a visiting lecturer in the Department of Statistics at the University of California, Berkeley during 1978-1979. Most of his time since then has been with the CSIRO Division of Mathematical and Information Sciences (CMIS), Sydney, where he is now a Chief Research Scientist. He led CMIS' Image Analysis Group from 1989 to 2000. He spent 1988 at the Melbourne Research Laboratories of Broken Hill Proprietary Ltd. where he established the Image Processing and Data Analysis Group. His research interests are in image analysis (especially hyperspectral), spectroscopy and spatial data analysis. Since 2007, Dr. Berman has been working part time at CMIS. During this period, he has also given Ph.D courses in spectroscopy and hyperspectral image analysis at the Technical University of Denmark and Stanford University.

Tip-enhanced Raman spectroscopy 2D cut of complete 3D simulations of gold tip and gold surface (tip-to-surface distance is 10 nm) excited by a laser pulse at 652 nm. Laser pulse propagates towards the screen and is polarized along tip's longer axis. Intensity is plotted in logarithmic scale and is normalized to it's maximum. Maximum intensity enhancement in this example is 4 orders of magnitude. Tags: nanoplasmonics plasmon resonance |
