ABSTRACT: Nuclear Magnetic Resonance (NMR) spectroscopy has made a tremendous impact in many areas of chemistry, biology and medicine. In this report a student-oriented approach is presented, which enhances the ability of students to comprehend the basic concepts of NMR spectroscopy and the NMR spectra of

Scope and Syllabus. The aim of this course is to introduce the basic concepts of one and two - dimensional NMR spectroscopy to graduate students who have used NMR in their daily research to enable them to appreciate the workings of their analytical tool and enable them to run experiments with a deeper understanding
