why tetramethyle silane is used as a standard in NMR spectroscopy?
Ans: Tetramethylsilane (abbreviated as TMS) is the organosilicon compound with the formula Si(CH3)4. It is the simplest tetraorganosilane. Tetramethylsilane is the accepted internal standard for calibrating chemical shift for 1H, 13C and 29Si NMR spectroscopy in organic solvents (where TMS is soluble) Because all twelve hydrogen atoms in a tetramethylsilane molecule are equivalent, its 1H NMR spectrum consists of a singlet.The chemical shift of this singlet is assigned as 0 (delta) δ or tau ( ʈ ) , and all other chemical shifts are determined relative to it.
