This site will be most useful for students with some introductory background in NMR. Nuclear Magnetic Resonance NMR is based on the behavior of a sample placed in an electromagnet and irradiated with radiofrequency waves: 60 – 900 MHz (l ≈ 0.5 m) The magnet is typically large, strong, $$$, and delivers a stable, uniform field – required for the best NMR data A transceiver antenna, called the NMR probe, is inserted into the center bore of the magnet, and Basic principles of NMR 2. The technique utilizes the fact that different CH-functions behave differently in an experiment, where the polarization is transferred from the proton to the carbon atom . Consequently, both techniques were acknowledged by a nobel prize. 2D Correlation Spectroscopy (COSY) Understanding COSY with Product Operators. By the introduction of additional spectral dimensions these spectra are simplified and some extra information is obtained. They can easily exceed 2000 atoms. A Brief Introduction to NMR . If we see the case of 2D-NMR spectroscopy this possesses two frequency axes with one intensity axis and this also generates a very crowded and complex spectrum for larger molecules like proteins. Harris. Part III (DEPT and 2D-Methods) DEPT-Introduction. Hence to overcome such problems of 1D NMR, a one more dimension is applied so called 2D NMR spectroscopy for assignment of peaks. In 1951, chemists realized that NMR spectroscopy could also be used to study the structures of organic compounds.

The invention of multidimensional spectra was the major leap in NMR spectroscopy apart from the introduction of FT-NMR. Video created by University of Manchester for the course "Introduction to Molecular Spectroscopy". The present text assumes some basic knowledge of 1 H-NMR spectroscopy. Recall that most 13C-NMR are acquired as proton decoupled spectra because of the 13C nucleus is significantly less abundant than the 1H nucleus (1.11 % (13C) vs. 99.85 % (1H)). Weiguo Hu .
