KJM5250 - Organic NMR Spectroscopy
Schedule, syllabus and examination date
Lectures include the following topics: Chemical shifts, coupling constants, relaxation (T1 and T2). Practical aspects for optimization of NMR experiments. Tuning and Matching. Shimming. Selection of acquisition and processing parameters. Information transfer via coupling constants and through space (Overhauser effect). One dimensional and two dimensional pulse sequences. The time dimensions t1 and t2. The frequency dimensions F1 and F2. “Window functions”. Intepretation of spectra. Rational choice of type of experiment, acquisition- and processing-parameters in relation to chemical problem. Vector and spin population models in explanation of NMR phenomena and the individual experiment. Inverse detected experiments. The laboratory course (one day each week for 10 weeks) includes the following NMR experiments which are performed by two or three students together. Pulse angle optimization, selective 1H - 1H decoupling, T1/T2 relaxation time determination, DEPT, NOEDIF, COSY, TOCSY, XHCORR (HETCOR), COLOC, HMBC or HSQC, HMBC, NOESY and ROESY. A new goal from the spring of 2010 is to enhance the competence of setting up new experiments without having a detailed instruction.
After completion of KJM 5250
- You will be able to make a rational choice of type of nmr-experiments for the nuclei; 1H, 13C,19F, 31P and 15N and combinations thereof and can choose and implement acquisition- and processing-parameters in relation to chemical problems.
- You will master vector and spin population models in explanation of nmr phenomena.
- You understand the concepts of tuning/matching and master the practical art of shimming.
- You will understand the concepts of T1- and T2-relaxation and you know how to measure them and how to set up and perform experiments to measure them.
- You understand the concepts of information transfer through electrons in bonds as well as through space via the Overhauser effect. You will understand and can explain the mechanism of the Overhauser effect.
- You understand the concepts of one- and two- dimensional pulse sequences as well as the time dimensions t1 and t2 and the frequency dimensions f1 and f2.
- You understand the concepts of and can apply “window functions” and “ linear prediction” in one and two dimensions.
- You understand the differences between inversely and directly detected experiments and know when to choose either of them.
- You will master: pulse angle optimization, selective 1H-1H decoupling, DEPT(45, 90, 135), COSY(GP), TOCSY(GP), XHCORR (HETCOR), COLOC, HSQC(EDETGP), HMBCGP, NOESY and ROESY experiments.
- You are able to interpretate and put together information from a series of nmr experiments in elucidation of chemical structures and problems.
Students who are admitted to study programmes at UiO must each semester register which courses and exams they wish to sign up for in Studentweb.
If you are not already enrolled as a student at UiO, please see our information about admission requirements and procedures.
Formal prerequisite knowledge
Recommended previous knowledge
KJM3000 - Applied spectroscopy, as well as practical knowledge in acquisition of one dimensional 1H- and 13C-NMR spectra with Bruker Avance instruments using the NMR program TopSpin 1.3. The NMR module in KJM-MENA4010 - Experimental methods (accessible for Master's students, and which normally runs immediately prior to KJM5250) is highly recommended.
10 credits overlap with KJM9250 - Organic NMR Spectroscopy
The course includes 20 hours of lectures and a laboratory course of 50 hours. The first lecture is mandatory. If you are unable to join, the Expedition Office has to be informed in advance (phone 22 85 54 46, or e-mail firstname.lastname@example.org). Approved laboratory course is a prerequisite for taking the exam.
As the teaching involves laboratory and/or field work, you should consider taking out a separate travel and personal risk insurance. Read about your insurance cover as a student.
The exam includes tests of practical skills in the laboratory as well as oral examination of theoretical knowledge. Approved laboratory course is a prerequisite for taking the exam.
Grades are awarded on a scale from A to F, where A is the best grade and F is a fail. Read more about the grading system.
Explanations and appeals
Resit an examination
This course offers both postponed and resit of examination. Read more:
Withdrawal from an examination
It is possible to take the exam up to 3 times. If you withdraw from the exam after the deadline or during the exam, this will be counted as an examination attempt.
Special examination arrangements
Application form, deadline and requirements for special examination arrangements.
The course is subject to continuous evaluation. At regular intervals we also ask students to participate in a more comprehensive evaluation.
