31P and 19F NMR

  1. Jan 5, 2007 #1
    We are using Varian Unity Inova 500 MHz NMR instrument.When we are taking 31P and 19F spectra we do not use any reference sample as like TMS etc. Our customer says us that they are not interpreting these spectras without reference. Which reference can we use for these spectras and how can we take these spectras with reference on the NMR?
    Could you please help us...

    Many thanks..
