A unique guide to variable temperature CD spectroscopy and its application in organic chemistry<br> This timely, original, thought-provoking work looks at organic stereochemistry from the perspective of circular dichroism (CD), using variable temperature CD spectroscopy to determine the conformation or absolute configuration of chiral molecules. With an emphasis on the analysis of optically active ketones and the carbonyl chromophore, the authors demonstrate the advantages of this highly sensitive spectroscopic tool for obtaining stereochemical information in diverse areas of organic chemistry, biochemistry, and medicinal/pharmaceutical chemistry. They combine detailed examples of stereochemical analysis with clear, thorough presentations, correlating chiroptical data with molecular mechanics calculations as well as data from NMR spectroscopy and other spectroscopic techniques. In addition, they provide a systematic survey of the professional literature, featuring an extraordinary collection of original CD spectra run at varying temperatures. Coverage includes:<br> * Chiroptical measurements: CD and ORD (Optical Rotatory Dispersion)<br> * Conformational analysis of compounds ranging from simple cyclic ketones to polycyclics<br> * Conjugated and homoconjugated systems<br> * Stereochemistry of the carbon-carbon double bond<br> * Stereochemistry from exciton coupling of two or more chromophores<br> * An interesting historical account of the development of stereochemical concepts
This is a single, comprehensive handbook for clinical oncology trainees and consultants, covering the basic aspects of stereotactic radiotherapy systems and treatment.
Throw them out and ratings skyrocket on cable TV. At church, you may fill a few more seats whenever you spice your sermon with them. In politics, they rally the base. In communities, they bond people with commonalities and keep at bay the deviant. In all cases, however, somebody pays for them, and lives with them, sometimes forever. In Stereotypes and Labels, Kirby A. Manager, PhD., uses real-life examples to show how tags, labels and stereotypes impact the lives of millions in communities around us. He explores how we all pay for it at the end.
