An explanation of how a mass spectrometer works is followed by a demonstration of a mass spectrometer in action. The analysis of simple mass spectra is discussed—simple splitting of hydrocarbons, the effect on splitting of heteroatoms in alcohols and ethers, and the McLafferty rearrangement. Discussion of the spectra of isotopic mixtures, such as chlorine and bromine, and the use of accurate masses is also included. (30 minutes)

		Interpreting Infrared and N.M.R. Spectra An explanation of the theory of infrared absorption is followed by showing a series of spectra demonstrating the major absorption peaks. Shifts within the carbonyl group, and their explanation, are discussed. The N.M.R. portion of the program covers ...(more details)		DVD $79.95 DVD + 3-Year Streaming $119.93 3-Year Streaming $79.95
		Oxidation Oxidation and reduction are discussed in terms of electron transfer, leading to the idea of electrode potentials. Illustrations are provided using the space shuttle, the Breathalyzer, a cannon, and a more complex electron transfer experiment. The pro...(more details)		DVD $79.95
		Ultraviolet Spectroscopy A discussion of the importance of ultraviolet/visible absorption in color vision leads on to the fundamentals of absorption resulting from the shift of an electron from a bonding to an antibonding orbital. The importance of conjugation is stressed, a...(more details)		DVD $79.95
		Intermediate H.N.M.R. Spectroscopy This program takes over where the program Interpreting Infrared and N.M.R. Spectra leaves off, covering shift reagents, deuterium exchange and decoupling, then proceeding to the splitting patterns observed in rigid molecules where the Karplus equatio...(more details)		DVD $79.95
		13C N.M.R. The importance of the low natural abundance of 13C is stressed in this program, showing how it influences the development of the subject. The program covers types of decoupling, the effect of chemical shift, and the effect of deuterium and 13C labels...(more details)		DVD $79.95 DVD + 3-Year Streaming $119.93 3-Year Streaming $79.95
