Description
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.

Description
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.

Description
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 the ideas of integration, chemical shift, and splitting in proton spectra in a logical process of development of the subject.
