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.

The microscope's role as an indispensable piece of laboratory equipment is well-recognized. This program illustrates the fundamentals of microscope use. Its six segments discuss the basic parts of a microscope, lighting techniques for maximum vision, preparing specimens for viewing, care of the microscope, and advanced techniques, such as the use of oil immersion and video microscopy.
13) Acids and bases
Language
English
Description
Use this video to familiarize students with the properties of acids and bases. Beginning with an overview of how these two kinds of chemicals react to or neutralize each other, the program explores Arrhenius's ideas on ion release and Lowry and Bronsted's theory of proton exchange. Details on the pH scale, indicators, conjugate bases, and Lowry-Bronsted reactions are featured along with numerous examples of acid and base applications-cleaning agents,...

Unlike what's seen on TV crime shows, forensic science often requires weeks or months to produce results, and-although it's far from boring-it rarely involves confronting a suspect. This program debunks pop-culture stereotypes and illuminates the real-world chemistry, biology, and physics of criminology. Exploring three main forensic science disciplines-field work, lab analysis, and medical examination-the program shows how crime scenes are defined...
