Molecular Spectroscopy: A Physical Chemist’s perspective

By Prof. Anindya Datta   |   IIT Bombay
Learners enrolled: 80
This is a comprehensive course on molecular spectroscopy. We start with dispersive and Fourier transform spectroscopic techniques, go on to derive selection rules from Time dependent perturbation theory, develop a quantum mechanical treatment of spin resonance spectroscopy and then move on to a discussion of spectra of polyatomic molecules using symmetry. This course is the same as CH 442 of IIT Bombay

INTENDED AUDIENCE : Chemistry, Physics and UG students of Engineering

Instructor bio

Prof. Anindya Datta

IIT Bombay
I am a Professor of Chemistry in IIT Bombay, with research interest in ultrafast spectroscopy and time resolved fluorescence microscopy. I have teaching experience of 17 years. 14 Ph. D. students have graduated from our laboratory. Eight more are working towards their degree. I received Excellence in Teaching Award from our institute in 2017 and have taught two NPTEL courses: one on Molecular Spectroscopy and another on Symmetry in Chemistry.

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 IIT Bombay.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.
