Notetaking slides are available for the entire presentation its usage is highly encouraged.Ĭhemistry 344 Spectroscopy and Spectrometry Pre-Laboratory Video Lecturesĭay 1 Videos (Ultraviolet/Visible Spectroscopy, Infrared Spectroscopy & Electron-Impact Mass Spectrometry) Viewing of the video lectures is required before attending the corresponding laboratory session. For each day additional links and textbook readings are provided. The laboratory section will begin with TA-led activities designed to reinforce and further develop the lecture video material. For each of the first four laboratory days, there are pre-recorded video lectures that must be watched prior to attending the laboratory session. The general schedule is detailed below as well as many useful links. In order to ensure that each student’s problem-solving skills are adequate to interpret the spectra produced in the course, the laboratory sessions are devoted to interpreting these spectra. As is often the case in organic chemistry research, 1H-NMR spectroscopy will be used more than the other techniques and is an important point of emphasis in this course. It is critical that you develop a working knowledge of how each of these techniques provides structural information about organic molecules.
1H-NMR spectroscopy, 13C-NMR spectroscopy, 19F-NMR spectroscopy, IR spectroscopy and GC-Mass spectrometry are used throughout CHEM 344 to analyze, interpret, and rationalize experimental results.
