Jaffar, M.; Zahid, Qazi – Journal of Chemical Education, 1988
Presents the construction aspects of a simple but reliable colorimeter made from locally available components. Notes the absorption range to be 400-750-nm. Lists seven experiments done on the instrument. (MVL)
Descriptors: Chemical Analysis, Chemistry, College Science, Equipment
Peer reviewed Peer reviewed
Hudson, Reggie L.; Pendley, Bradford D. – Journal of Chemical Education, 1988
Describes an advanced NMR project that can be done with a 60-MHz continuous-wave proton spectrometer. Points out the main purposes are to give students experience in second-order NMR analysis, the simplification of spectra by raising the frequency, and the effect of non-hydrogen nuclei on proton resonances. (MVL)
Descriptors: Chemical Analysis, Chemistry, College Science, Inorganic Chemistry
Peer reviewed Peer reviewed
Boggess, Robert K. – Journal of Chemical Education, 1988
Describes a method for using nuclear magnetic resonance to observe the effect of electronegativity on the chemical shift of protons in similar compounds. Suggests the use of 1,3-dihalopropanes as samples. Includes sample questions. (MVL)
Descriptors: Chemical Analysis, Chemistry, College Science, Experiments
Peer reviewed Peer reviewed
Hill, Devon W.; And Others – Journal of Chemical Education, 1988
Describes a laboratory technique for quantitative analysis of caffeine by an isotopic dilution method for coupled gas chromatography-mass spectroscopy. Discusses caffeine analysis and experimental methodology. Lists sample caffeine concentrations found in common products. (MVL)
Descriptors: Chemical Analysis, Chemistry, Chromatography, College Science
Peer reviewed Peer reviewed
Arnold, Dennis P. – Journal of Chemical Education, 1988
Attempts to show that in the closed loops of cyclic structures the protons situated in conic regions above and below the ring will be shielded. Uses the diamagnetic and air stable octahedral tin(IV) complexes of porphyrins for study. Notes complexes crystallize easily and offer spectacular purple colors. (MVL)
