In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called A practical approach to three-dimensional NMR spectroscopy, published in 1987-07-31, which mentions a compound: 600-05-5, Name is 2,3-Dibromopropionic acid, Molecular C3H4Br2O2, Category: piperidines.
A technique is described for reducing the number of 3D experiments without sacrificing resolution by using selected pulse sequences. A method is described for reduction of the number of data matrixes. Applications of 3D spectrometry are described. Results are reported for 2,3-dibromopropionic acid.
