In a Course which is meant for the discussion of "Structure Determination by NMR" the following presentation files can be helpful to choose from and highlight the relevant NMR technical aspects at appropriate stages. Links below added on Saturday, March 29, 2008 at 7:41AM
This course content is drafted specifically to introduce and explain the basics of NMR Phenomenon and Technique.
At this stage the advances made in NMR as a tool for structure detrmination are not narrated, but the scope of this content includes these advances
(without specifically mentioning the specific names of such technical aspects) by specially stressing the basic aspects which are getting an importance at the stage of
trying to grasp the advanced techniques.Purpose had been to emphasize and highlight such topics in basic Science streams which are covered at a
much earlier stages of educational levels.This is essentially providing a strong foundation for enabling a quick grasp as and when the front line reports
are available on this technique. This text inscribed on Saturday, March 29, 2008 at 9:21AM

Standard books on Magnetic resonance Spectroscopy available in the libraries can be used as reference course materials. The original articles by the inventors in this technique are suggested for reading which must be found from the list of bibliographies available from the reference lists in Standard Text Books 
EXAMINATIONS and EVALUATION:
It is intended to have three sessional and one final examinations for grading purposes.
Further it is being proposed to have three or four unconventional tests/exams like the open Book examinations OR discuss a typical question paper in the classroom and specify a time duration where this question paper would be distributed to the students and answer as a conventional exmination paper. These would not be included in the markings for the Grading but absences at these additional Exams would cost the students heavily in attendance markings by including a negative attendance for defaults at these Exams. It could be that in a 45 Class attendance each absence in the Additional Exams would cost the students Three to Five classes in attendances and in the stipulated number of attendancerequirements the students would not be eligible for final certificate even if they had regularly attended other lectureclasses and Gradable Exams.
By such examination methods the Examiner and the Instructor can try to find out the difficulties of the students by the mock exams which are mandatory like the lecture classes, with better importance.
