Only one isotope is observed at a time because the spectrometer transmits and receives over a very limited frequency range. This, combined with the low natural abundance of c, means that it is much more difficult to observe carbon signals. The c nmr measurement techniques can be considered under two main groups. This is just one of the solutions for you to be successful.

Carbon c nuclear magnetic resonance most commonly known as carbon nmr or c nmr or sometimes simply referred to as carbon nmr is the application of nuclear magnetic resonance nmr spectroscopy to carbon. This organic chemistry video tutorial provides a basic introduction to nmr spectroscopy. There are three isotopes of hydrogen used in nmr spectroscopy. Thus, unless your compound does not have useful 1h signals, you will usually measure many more 1h than c nmr spectra. The spectrum is more complicated due to interactions between overlapping resonances.

Introduction to nmr spectroscopy swiss institute of bioinformatics i. Basic 1h and cnmr spectroscopy elsevier, 2005 author. Some nuclei experience this phenomenon, and others do not, dependent upon whether. Nmr spectroscopy basic principles each level has a different population n, and the difference between the two is related to the energy difference by the boltzmman distribution. The techniques applied to the measurement of c nuclei are different to those for protons. The magnetic moment of a c nucleus is much weaker than that of a proton, meaning that nmr signals from c nuclei are inherently much weaker than proton signals. Process nmr associates llc, 87a sand pit rd, danbury ct 06810 nuclear magnetic resonance spectroscopy nmr was first developed in 1946 by research groups at stanford and m. Description nuclear magnetic resonance nmr spectroscopy is a powerful and theoretically complex analytical tool.
