In a modern NMR spectrometer all frequencies are derived from a single source, so all chemical shifts can be determined relative to TMS (or relative to DSS in ... ,Tetramethylsilane (abbreviated as TMS) is the organosilicon compound with the formula Si(CH3)4. It is the simplest tetraorganosilane. Like all silanes, the TMS framework is tetrahedral. TMS is a building block in organometallic chemistry but also finds us
