This 3-day course will help you determine unknown molecular structures from infrared spectra. The course begins with how molecules absorb infrared radiation, and what peak positions, heights, and widths mean. Next, a systematic, 12-step method to successfully interpret spectra is presented. The bulk of the course is a discussion of the diagnostically useful infrared bands of economically important molecules including alkanes, aromatics, alcohols, esters, and amines. Special discussions of polymers and inorganics are included. The course concludes with a practical discussion of how library searching and spectral subtraction make interpreting mixture spectra faster and easier. Dozens of reference spectra will be reviewed in detail. Students will practice interpreting many unknown spectra in class under the guidance of your expert instructor.
Dr. Brian C.Smith has over 30 years experience as an infrared spectroscopist and has trained thousands of people in the field since 1992. He is the author of three popular books on spectroscopy; Fundamentals of FTIR and Infrared Spectral Interpretation published by CRC Press and Quantitative Spectroscopy: Theory and Practice published by Academic Press. Dr. Smith earned his Ph.D. in Chemistry from Dartmouth College and graduated summa cum laude from Rochester Institute of Technology with a B.S. in Chemistry.
Course Registration is available. You may also register through an associated conference registration. Send it with a payment of $2550 to secure your course attendance. Hotel information and a map will be sent to confirm your registration. Please list your special interest(s) on the registration form. Enrollment is limited to assure your maximum course benefits.
