It is not often realized by chemists that the special theory of relativity is behind several aspects of quantum chemistry. The Schrdinger equation itself is based on relations between space-time and energy-momentum four vectors. Electron spin is, of course, the most obvious manifestation of relativity. The chemistry of some heavy elements is…

Describes the construction and operation of an apparatus used to study the optical properties of solids using reflection. (JRH)

Using fourier transformation methods in nuclear magnetic resonance has made possible increased sensitivity in chemical analysis. This article describes these methods as they relate to magnetization, the RF magnetic field, nuclear relaxation, the RF pulse, and free induction decay. (CW)

A simple experiment concerning the elasticity of wood is described that can easily be performed at home. The forces needed to produce a stress in wood are measured and compared. Provides a mathematical discussion of the elasticity and stress of wood. (MVL)
