MICROCOMPUTER INSTRUCTION IN PROTON NMR SPECTRA INTERPRETATION. Kersey A. 479 Blaak, Joint Science Center, Claremont McKenna, Scripps and Pitzer Colleges, Claremont, California 91711. Proton NMR spectroscopy is the mainstay of organic qualitative analysis, and as such receives considerable attention in introductory organic chemistry courses. Software has been developed which helps exercise the users ability to :orrelate proton NMR spectra with molecular structure. The user can design and create organic structures on the screen of a MacintoshT14 microcomputer using the mouse to select from a palette af molecular pieces. Alkanes, alkenes, aromatics, halides, alcohols, ethers, ketones, aldehydes, acids, esters, amines, and amides can all be easily constructed in this manner. The program then generates a simulated proton NMR spectrum using empirically based rules for chemical shift calculation and assignment of coupling constants. Any of several common Lield strengths are possible, and the spectrum can be expanded, scrolled, and integrated. Correlations between protons and signals in the spectrum can be revealed, along with a "splitting tree" showing the results of spin-spin coupling for a particular signal. Files of compounds can be created and stored on disk such that the structure can be either "known" or "unknown" to the user. The simulation provides a spectrum reflecting first- and some second-order effects. Multiple spectra can be displayed in separate windows. v r.. CONTEXT:SCIENCE TEACHING IN ENGLAND.David Waddington, Alan Marsden, Christie BorRford, Marm Beth Kem, University of York, Dept. of Chemistry, University of York, Science Education Group, Heslington, York, YOl 5DD, England Teaching materials produced by teams of classroom teachers, chemists and science educators in England are activity and lab-based and tied to the context of the real world. Student and teacher interest is high when experiencing such science as percent water in "slimmers" margarine, making alloys for special uses and designing appropriate symbols for vehicles transporting chemicals. Advanced-level chemistry concepts arise I from real-world problems. Criteria are tied to the British National Curriculum and materials are presented as lesson designs with ready to use student activity guides. material originated with funding from the Salters' Foundation and, thus, is known as I Salters' Chemistry and Salters' Science. I POLYMER END-GROUP ANALYSIS IN THE QUANTITATIVE ANALYSIS I 481 LABORATORY. K. R. Williams and U. R. Bernier, Department of Chemistry, I University of Florida, Gainesville, FL 32611-2046. Beginning analytical laboratory students are introduced to the concept of number-average molecular weight via an experiment on end-group analysis of poly(ethylene glycol). The hydroxyl I groups are esterified by reaction with a known excess of 1,2,4,5-benzenetetracarboxylic dianhydride (pyromellitic dianhydride, PMDA) in DMF using imidazole (IMDA) as the catalyst'. Af*.er the reaction the remaining anhydride is hydrolyzed and the carboxylic acid residues are I titrated with standard base. The esterification reaction is complete in about 30 minutes at room temperature, and the subsequent hydrolysis is very rapid. There is a problem in some samples with precipitation of the salt of PMDA aad IMDA, and methods to avoid this side-reaction are I being investigated. Student results for several molecular weight distributions will be summarized in the oral presentation. I 'Kingston, B. H. M.; Garey, J. J.; Hellwig, W. B. Anai. Chem. 1969, 41, 86. I 482 USING HPLC IN INSTRUMENTAL ANALYSIS. Wade Tornquist, Department of Chemistry. I Eastern Michigan University, Ypsilanti. MI 48197. IHPLC simulates a binary gradient high-performance liquid chromatography instrument an d includes sophisticated modeling of reversed-phase column behavior. The modeling provides realistic chromatographic output over a broad range of operating conditions. The program has been rased as a pre-laboratory exercise for students who will later be using the real instrument, and also o extend the range of experience available to students after they have interacted with the real instrument. In particular the program's computer data station provides better data analysis than msto teaching instruments
