Carbon-13 NMR Spectroscopy
This organic chemistry video tutorial provides a basic introduction into carbon-13 NMR spectroscopy. It covers broadband decoupled C-NMR where all signals appear as singlets as well as proton-coupled C-13 NMR spectroscopy where the signals appear as doublets, triplets, and quartets based on the N+1 rule splitting pattern of the hydrogen atoms that are directly attached to the carbon atoms. It also discusses DEPT C-13 NMR spectroscopy which is useful for identify C, CH, CH2, and CH3 carbons. This video explains how to assign the chemical shifts to different carbons given the C-13 NMR spectrum as well as proposing a structure given the molecule and using factors such as IHD and the number of signals present in the spectrum. Finally, this video discusses the different chemical shifts of functional groups such as alkyl groups like methyl, methylene, and methine groups as well as halogens, amines, alkenes, alkynes, ethers, alcohols, benzene rings, aldehydes, ketones, esters, and carboxylic acids.

How to interpret a NOESY NMR spectrum
In this tutorial we look at how to interpret a NOESY NMR spectrum using a tripeptide as an example. 2D homogeneous NOE spectroscopy (NOESY) is a widely used experiment for looking at dipolar coupling between homonuclei such as H-H coupling. Because it relies on intramolecular (through space) interactions rather than through bond interactions it is extremely useful for assigning connectivities between spin systems and also for confirming the 3D structure of molecules.

NMR spectroscopy
NMR spectroscopy lecture by Suman Bhattacharjee - This lecture explains about the NMR spectroscopy basics. Nuclear magnetic resonance spectroscopy, most commonly known as NMR spectroscopy, is a research technique that exploits the magnetic properties of certain atomic nuclei. It determines the physical and chemical properties of atoms or the molecules in which they are contained. It relies on the phenomenon of nuclear magnetic resonance and can provide detailed information about the structure, dynamics, reaction state, and chemical environment of molecules. The intramolecular magnetic field around an atom in a molecule changes the resonance frequency, thus giving access to details of the electronic structure of a molecule. Most frequently, NMR spectroscopy is used by chemists and biochemists to investigate the properties of organic molecules, although it is applicable to any kind of sample that contains nuclei possessing spin. Suitable samples range from small compounds analyzed with 1-dimensional proton or carbon-13 NMR spectroscopy to large proteins or nucleic acids using 3 or 4-dimensional techniques. The impact of NMR spectroscopy on the sciences has been substantial because of the range of information and the diversity of samples, including solutions and solids. NMR spectra are unique, well-resolved, analytically tractable and often highly predictable for small molecules. Thus, in organic chemistry practice, NMR analysis is used to confirm the identity of a substance. Different functional groups are obviously distinguishable, and identical functional groups with differing neighboring substituents still give distinguishable signals. NMR has largely replaced traditional wet chemistry tests such as color reagents for identification. A disadvantage is that a relatively large amount, 2–50 mg, of a purified substance is required, although it may be recovered. Preferably, the sample should be dissolved in a solvent, because NMR analysis of solids requires a dedicated MAS machine and may not give equally well-resolved spectra. The timescale of NMR is relatively long, and thus it is not suitable for observing fast phenomena, producing only an averaged spectrum. Although large amounts of impurities do show on an NMR spectrum, better methods exist for detecting impurities, as NMR is inherently not very sensitive. NMR spectrometers are relatively expensive; universities usually have them, but they are less common in private companies. Modern NMR spectrometers have a very strong, large and expensive liquid helium-cooled superconducting magnet, because resolution directly depends on magnetic field strength. Less expensive machines using permanent magnets and lower resolution are also available, which still give sufficient performance for certain application such as reaction monitoring and quick checking of samples. There are even benchtop NMR spectrometers. This important and well-established application of nuclear magnetic resonance will serve to illustrate some of the novel aspects of this method. To begin with, the nmr spectrometer must be tuned to a specific nucleus, in this case the proton. The actual procedure for obtaining the spectrum varies, but the simplest is referred to as the continuous wave (CW) method. A typical CW-spectrometer is shown in the following diagram.

21.1 High resolution 1H NMR (HL)
Understandings: In a high resolution 1H NMR spectrum, single peaks present in low resolution can split into further clusters of peaks. Guidance: Students should be able to interpret the following from 1H NMR spectra: number of peaks, area under each peak, chemical shift and splitting patterns. Treatment of spin-spin coupling constants will not be assessed but students should be familiar with singlets, doublets, triplets and quartets.
