WebIn general, when you start analyzing a 13 C NMR, split the spectrum in two parts by drawing a line at 100 ppm; below this value you have the saturated functional groups, and beyond that is the unstructured region. Saturated … 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.

WebThis condition can be summarized in equation (2) form as follows: (2) Vibrations that satisfy this equation are said to be infrared active. The H-Cl stretch of hydrogen chloride and the asymmetric stretch of CO 2 are examples of infrared active vibrations. Infrared active vibrations cause the bands seen in an infrared spectrum.

WebNMR spectroscopy produces graphs called spectra. Spectra show energy absorbed against a value called chemical shift. To read them, you look at the peaks produced on the graph and compare their chemical shift values to those in a data table to help you identify the molecule's structure.
