WebNMR spectroscopy is an analytical technique that scientists use to work out the structure of different molecules. NMR spectroscopy stands for nuclear magnetic resonance … When placed in a magnetic field, NMR active nuclei (such as H or C) absorb electromagnetic radiation at a frequency characteristic of the isotope. The resonant frequency, energy of the radiation absorbed, and the intensity of the signal are proportional to the strength of the magnetic field. For example, in a 21 Tesla magnetic field, hydrogen nuclei (commonly referred to as protons) resona… WebThose peaks represent the wavelengths of infrared light that don't get to the detector, because there's some functional group in the sample absorbing them.

Webthere has to be an uneven number of protons (and or?) neutrons in order for the nucleuss to have spin. You can only detect nuclei that have spin with the NMR machine. It so happens that over 99% of Hydrogen is H-1 (one is an odd number) and over 99% of C is C-13 (odd number again). So it makes sense that these would be easy to detect.
