Palmer, W. P. – Online Submission, 1994
This short article consists of some thoughts derived from a longer paper (Palmer, 1992), together with some more recent ideas. I became interested in buckminsterfullerene (Buckyballs) as a result of an E-Mail discussion of the topic in 1991. The chemistry of buckyballs is now evolving very rapidly and is gradually creeping into school…

Baker, William P.; Jones, Carleton Buck; Hull, Elizabeth – Online Submission, 2004
Understanding the structure and function of proteins is an important part of the standards-based science curriculum. Proteins serve vital roles within the cell and malfunctions in protein self assembly are implicated in degenerative diseases. Experience indicates that this topic is a difficult one for many students. We have found that the concept…

Feldmann, Richard J.; And Others – Journal of Chemical Documentation, 1972
Computer graphics provides a valuable tool for the representation and a better understanding of structures, both small and large. Accurate and rapid construction, manipulation, and plotting of structures, such as macromolecules as complex as hemoglobin, are performed by a collection of computer programs and a time-sharing computer. (21 references)…

Bright, J. W.; Chen, E. C. M. – Journal of Chemical Education, 1983
Describes a simple method to determine potential chemical formulas for a given molecular weight and to calculate all of the typical mass spectrometric parameters which can be obtained experimentally. Calculated values can then be compared to experimental values to obtain the most reasonable formula. (JN)

DeVore, Thomas C.; Gallaher, Thomas N. – Journal of Chemical Education, 1983
Describes a physical chemistry experiment which uses group theory to help interpret the infrared spectrum of a polyatomic molecule with Td symmetry (spherical tops). Topics covered in the experiment: background information and theory, experimental procedures, and typical student results. (JN)

Castano, F.; And Others – Journal of Chemical Education, 1983
The RKR method for determining accurate potential energy curves is described. Advantages of using the method (compared to Morse procedure) and a TRS-80 computer program which calculates the classical turning points by an RKR method are also described. The computer program is available from the author upon request. (Author/JN)

Natarajan, L. V.; And Others – Journal of Chemical Education, 1983
Provides background information, procedures, and results of an undergraduate physical chemistry experiment on the polarization of absorption spectra of cyanine dyes in stretched polyvinyl alcohol films. The experiment gives a simple demonstration of the concept of linear dichromism and the validity of the TEM method used in the analyses. (JN)

Pacey, Philip D. – Journal of Chemical Education, 1981
Provides background material which relates to the concept of activation energy, fundamental in the study of chemical kinetics. Compares the related concepts of the Arrhenius activation energy, the activation energy at absolute zero, the enthalpy of activation, and the threshold energy. (CS)

Blake, P. G.; Clack, D. W. – Journal of Chemical Education, 1982
Thermochemical cycles are used to decide which hypothetical compounds might exist and, if not, what is the factor that condemns them to non-existence. Hypothetical compounds of rare gases provide examples of the approach with added historical interest that thermochemical considerations led to prediction and demonstration that XePtF-6 was stable.…
