INTERESTING..Why Tms Is Used As Reference In Nmr Spectroscopy
A method which is still acceptably used today The TMS peak lies outside the usual spectral region and is readily identifiable It is largely inert. Tetramethylsilane became the established internal reference compound for 1H NMR because it has a strong sharp resonance line from its 12 protons with a chemical shift at low resonance frequency relative to almost all other 1H resonances.

Most common methods at the time used an external reference such as a coaxial insert.
Why tms is used as reference in nmr spectroscopy. Uses in NMR spectroscopy Because of its high volatility TMS can easily be evaporated which is convenient for recovery of samples analyzed by NMR.
