The difference of a 300 MHz and 900 MHz NMR is the relationship of the ppm to Hz. For 300 MHz instrument, 1 ppm is equal to 300 Hz and for a 900 MHz instrument, it corresponds to 900 Hz. Now, if two protons give almost identical signals with the 300 MHz instrument, let’s say the difference is only 15 Hz, it is very difficult to tell the signals apart since they are overlapping:

Chemical Shift Values. As already mentioned, the resonance frequency giving the signal in NMR, and indicating the types of protons, is shown on the x axis by δ (delta). The 0 ppm is a reference point where the protons of tetramethylsilane, (CH3) 4 Si, also called TMS give signal. affect the hydrogens: add the indicated values from the table together, add the correction for the methylenyl or methinyl hydrogen, and subtract 0.9 from the total.
