One and two dimensional NMR Spectroscopy for chemists

By Prof. N. Suryaprakash   |   IISc Bangalore
Learners enrolled: 450
In this course, I will discuss fundamental concepts of NMR spectroscopy, experimental determination of NMR spectral parameters, their interpretation, selective and broadband homo and Heteronuclear spin decoupling, numerous examples of the analysis of NMR spectra of 1H, 13C and other heteronuclei will be given. The relaxation processes, their measurement and utility in understanding molecular dynamics, the polarization transfer mechanism, the spectral editing techniques, such as, APT, DEPT, INEPT will also be discussed. Two dimensional NMR and the commonly employed experiments, viz., COSY, TOCSY, HSQC, HMQC, HMBC, NOESY, etc will be discussed with number of examples. The practical aspects of one and two dimensional NMR data acquisition and processing will also be highlighted. The solid state NMR, magic angle spinning and cross polarization will also be discussed.

Instructor bio

Prof. N. Suryaprakash

IISc Bangalore
Prof. N. Suryaprakash has been carrying out research in NMR spectroscopic methodological developments and applications. His research achievements have received world wide recognition, appearing in more than 150 publications in peer reviewed journals of National and International repute, which include several invited book chapters and presented the work in more than 140 occasions in various meetings around the world. His research work is focused on diverse wings of NMR spectroscopy, with a major focus on the manipulation of spin dynamics to design novel NMR techniques to combat inherent challenging problems of NMR spectroscopy, viz., to achieve sensitivity enhancement, higher resolution, discerning of degenerate transitions and facile extraction of spectral information. His designed single and multiple quantum methodologies significantly transformed chiral analysis of molecules in weakly aligned media using 1H NMR, a field that remained unchallenged for decades. He has also discovered numerous water compatible weak chiral aligning media that circumvented many inherent limitations of enantiomeric differentiation. He has introduced number of novel chiral auxiliaries, for enantiodiscrimination of molecules with diverse functionalities, accurate determination of enantiopurity and also for the assignment of their absolute configurations. His innovative NMR approaches for investigation of hydrogen bond involving organic fluorine, paves the way for the artificial architectural design of macromolecules. His seminal contributions have catapulted research in NMR spectroscopy, structural chemistry, chiral chemistry and in the field of weak molecular interactions. The quality and innovative character of his work has received several distinctions, viz. G V Bakore Memorial Award of Indian Chemical Society (2015), Tata Chem Chair Professorship (2015) of IISc, President National Magnetic Resonance Society (2015), Adjunct Professorship, Poornaprajna Institute of Scientific Research, Bangalore (2009), Fellowship of the National Academy of Sciences (2005), Sir C.V. Raman Award of Karnataka Government (2001), Young Scientist award of the Karnataka Association for the Advancement of Science (1994). Bruker Young NMR Scientist award (1987). In his highly popular Nation Building and Human Resource Development Activities, he has organized numerous schools and workshops, delivered several hundreds of educative lectures all across the country and abroad to disseminate the knowledge on NMR spectroscopy to college students, young researchers and practicing scientists, which is always greatly enjoyed by all the participants.
