Four examples are given of spectra of organophosphorus compounds which show students how the effects of phosphorus are delt with in nmr spectroscopy. (BB)

Describes a currently used picosecond spectroscopy system capable of reliably recording picosecond events. Two areas of picosecond research are discussed: one concerns the interaction of electrons in fluids; the second, the primary events in vision. (Author/HM)

Provides a chronicle of the use of luminescence spectrometry as an analytic device. Describes present-day applications of the technique. (CP)

Discusses the determination of the position of the absorption maximum in wide bands as well as the confidence limits for such calculations. A simple method, suited for pocket calculators, for the numerical evaluation of these calculations is presented. (BB)

Describes an experiment designed to familiarize students with the operation of a precision spectrophotometer, the effects of changes in operating variables, and the characteristics of such components as sources and detectors. (SLH)

Presents an experiment involving the identification of FD&C dyes by visible spectroscopy. (SL)

Presents a review of currently available technology of new trends in liquid chromatography-mass spectrometry. (BB)

Provides a discussion which is intended for chemistry college students on the ion cyclotron resonance (ICR) spectroscopy, the physical basis for ion cyclotron resonance, and the experimental methodology employed by ICR spectroscopists. (HM)

Describes the application of a computer program designed to produce a formula determination simultaneously accounting for both elemental composition and probable isotopic species for a measured ion mass. (SLH)

Describes the use of atomic spectra that are excited in inductively coupled plasmas for the simultaneous or sequential determination of the elements at all concentration levels. (HM)

Discusses how trace elements are determined in soils and plants and accounts for some of the effects observed. (BB)
