Infrared Spectroscopy Courses The University of Minnesota will offer two courses in infrared spectroscopy. The first course, "Techniques of Infrared Spectroscopy," will be held from July 30 to Aug. 30, followed by the second course, "Chemical Interpretation of Infrared Spectra," from Aug. 5 to 9. The courses are related but participants may register for either or both. The lecture courses begin with the fundamentals and carry through to include recent developments; discussion seminars provide opportunity for treatment of advanced topics. Participants should have at least basic training in chemistry and physics, but not necessarily experience in spectroscopy. Enrollment for each course is limited; those interested should write to the Director, Center for Continuation Study, University of Minnesota, Minneapolis 14, Minn.
