The book Organic Spectroscopy deals with UV-Visible, IR, 1H NMR, 13C NMR, and mass spectrometry along with spectroscopic solution of the structural problems. The book covers the basic theory, instrumentation and the structure-spectra correlations of the major spectroscopic techniques. In addition, the book acquaints students with the methods to determine the structure of an unknown compound in a (reasonably) logical manner with the help of all major spectroscopic techniques. The authors aim to provide spectra to illustrate every point made, but do analyze fully each of the spectra in order to obtain the maximum information available. Learning by solving problems gives more competence and confidence in the subject. So, the book includes, wherever required, numerous solved and unsolved problems that will help students to understand the concepts easily and obtain “structures from spectra”. The book is; therefore, a collection of such problems to help students acquaint with the basics of spectroscopy.
