ABOUT THE COURSE: The objective of the course, “Interpretative Molecular Spectroscopy” is to make the students familiar with important spectroscopic methods such as, NMR, UV-visible, IR and mass spectrometry to analyze and interpret the data without any ambiguity. This course elaborates on multinuclear NMR and how effectively one can use the data to assess the reactivity and also to get information about the reaction mechanism. Simple method is used to teach the interpretation of spectral data by choosing numerous examples taken from research articles and also from our own research group. This course is very useful for Synthetic Chemists in Research and Industries, Biological Chemists, Natural Product Chemists, Forensic Chemists and also Environmental Chemists and BSc/MSc/PhD students.INTENDED AUDIENCE: Students studying BSc/MSc/PhD and Biotechnology, chemists working in chemical industries/R&D units.PREREQUISITES: Even students with 12th grade knowledge can take this. Those who are studying BSc, MSc and also PhD students can take this.INDUSTRY SUPPORT: This course comes very handy to those who work in chemical/pharmaceutical industries.
