Instructor bio

Prof. N. Suryaprakash

IISc Bangalore
N. Suryaprakash, is a professor and the current chairman, NMR Research Centre, Indian Institute of Science. 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. He has also discovered numerous water compatible weak chiral aligning media that circumvented many inherent limitations of enantiomeric differentiation. His seminal contributions have catapulted research in NMR spectroscopy, structural chemistry, chiral chemistry and in the field of weak molecular interactions

Course certificate

The course is free to enroll and learn from. But if you want a certificate, you have to register and write the proctored exam conducted by us in person at any of the designated exam centres.
The exam is optional for a fee of Rs 1000/- (Rupees one thousand only).
Date and Time of Exams: 24 April 2022 Morning session 9am to 12 noon; Afternoon Session 2pm to 5pm.
Registration url: Announcements will be made when the registration form is open for registrations.
The online registration form has to be filled and the certification exam fee needs to be paid. More details will be made available when the exam registration form is published. If there are any changes, it will be mentioned then.
Please check the form for more details on the cities where the exams will be held, the conditions you agree to when you fill the form etc.

CRITERIA TO GET A CERTIFICATE

Average assignment score = 25% of average of best 8 assignments out of the total 12 assignments given in the course.
Exam score = 75% of the proctored certification exam score out of 100

Final score = Average assignment score + Exam score

YOU WILL BE ELIGIBLE FOR A CERTIFICATE ONLY IF AVERAGE ASSIGNMENT SCORE >=10/25 AND EXAM SCORE >= 30/75. If one of the 2 criteria is not met, you will not get the certificate even if the Final score >= 40/100.

Certificate will have your name, photograph and the score in the final exam with the breakup. It will have the logos of NPTEL and IISc Bangalore.It will be e-verifiable at nptel.ac.in/noc.

Only the e-certificate will be made available. Hard copies will not be dispatched.

Once again, thanks for your interest in our online courses and certification. Happy learning.
