A Strategy for Incorporating 13C NMR into the Organic Chemistry Lecture and Laboratory Courses Perry C. Reeves and Chris P. Chaney
The use of spectroscopy in establishing the structures of molecules is an important component of the first course in Organic Chemistry. However, the point in the course at which these techniques are best introduced remains uncertain. We suggest that carbon nuclear magnetic resonance spectroscopy should be introduced at an early stage of the lecture course, specifically while studying the alkanes, and used extensively for structure determination throughout the course.
