Outlined is a procedure for analyzing the ground electronic state of the iodine molecule by using information provided by "hot" bands, observed in the absorption spectrum of iodine vapor. (RH)

Described are infrared windows made from Tupperware and polyethylene coffee can lids that provide acceptable spectra for low-frequency infrared. (RH)

Described is a quick, easy, and cheap, but effective method of obtaining infrared spectra of solids and nonvolatile liquids by Fourier transform infrared spectroscopy. The technique uses tissue paper as a support matrix. (RH)

Described is an alternative method to infrared spectroscopy for the quantification of xylene mixtures. The method employs nuclear magnetic resonance spectroscopy. (RH)

Uses a diode array spectrometer to explain why blue objects appear red when viewed through the yellowish amber lens of "blue blocking" sunglasses. (JRH)

Summarizes the content of a lecture in which relativistic effects in chemistry are introduced through a calculation that illustrates these effects on the s and p electrons and that can be verified by photoelectron spectroscopy data. (JN)

Describes an approach which provides a basis for developing skills in interpreting infrared spectra and gives students a methodology which is functional without having to match "problem" spectra with "published" spectra. In addition, the suggested approach is reinforced easily by laboratory exercises involving known or unknown…

Discusses problems associated with standard diffraction grating experiments involving a diffraction grating, a straight meter stick, and a slit. Describes the use of a new spectroscope to overcome these problems using a curved scale to simplify calculations and help students obtain results from simple and straightforward measurements, thus giving…

Presents and discusses a procedure for estimating the dissociation energies of diatomic molecules by taking into account experimentally observable parameters. (CS)

Describes two demonstrations for use in college chemistry classes. Includes "Spectroscopy in Large Lecture Halls" and "The Endothermic Dissolution of Ammonium Nitrate." Gives materials lists and procedures as well as a discussion of the results. (CW)

Presented are flow charts to help students interpret infrared and nuclear magnetic resonance spectra of simple organic compounds. Advantages in using these charts are outlined. (JN)

Describes an instructional experiment that was designed to illustrate the use of periodate oxidation in sugar analysis, and the consequence that the absorbance of mixtures of non-interacting substances is additive. (TW)

Described is a laboratory exercise that uses nuclear magnetic resonance to monitor enantiomeric excess in asymmetric reductions. The laboratory exercise has been used successfully with undergraduate organic chemistry students. (RH)

Presents a design for constructing a colorimeter as an alternative to the more expensive spectrophotometer. The materials cost less than $25.00. (PR)

Provides sample output and describes a program for programmable calculators that determines the molecular parameters of any type of diatomic molecule. (CS)
