"WebThere are a few reasons why TMS is used as a reference. First, it is a rear example of a carbon connected with a less electronegative element, silicon, which makes it shielded and therefore appear at lower ppm where other protons do not give signal and the peak at 0 ppm can be ignored when analyzing an NMR spectrum.
