Carbon – 13 NMR
- Application of nuclear magnetic resonance (NMR) spectroscopy for identifying carbon atoms in organic compounds
- Can detect isotopes of carbon that are not naturally abundant, for example 13
- The effect of this is that a C-13 nucleus can behave as a little magnet. C-12 nuclei don’t have this property.
- Analytical technique used for identification of unknown materials in a sample, for quantifying known samples and for elucidating the structure of a variety of chemical compounds.
- A mass spectrometer generates multiple ions from the sample under investigation and separates them according to their specific mass-to-charge ratio (m/z), and records the relative abundance of each ion type.
- Commonly used in analytical laboratories to study physical, chemical and biological nature of different compounds.
- Based on absorption spectroscopy techniques, interaction spectroscopy involves the interaction of infrared with matters.
- This can be analysed in three ways by measuring absorption, emission and reflection.
- Widely used analytical technique in both organic and inorganic chemistry, quality control, dynamic measurement, forensic analysis etc.
