The majority of compounds studied by H NMR spectroscopy absorb downfield of the TMS signal, thus there is usually no interference between the standard and the sample. Similarly, all four carbon atoms in a tetramethylsilane molecule are equivalent. In a fully decoupled C NMR spectrum, the carbon in the tetramethylsilane appears as a singlet, allowing for easy identification. The chemical shift of this singlet is also set to be

Because all twelve hydrogen atoms in a tetramethylsilane molecule are equivalent, its H NMR spectrum consists of a singlet. The chemical shift of this singlet is assigned as
