What is zero filling in NMR?

Zero-Filling is the process of adding data points to the end of the FID before Fourier Transform. Zero-Filling can improve data quality by increasing the amount of points per ppm in the processed data to better define the resonance.

What is 0 fill?

Definitions: To fill unused storage locations in an information system with a numeric value of zero.

What will using a zero fill or interpolation technique to reduce scan time also reduce?

Zero filling processes can be very practical in everyday clinical usage by reducing scanning times without much loss in resolution or SNR, since zero filled points contain neither signal nor noise.

What causes peaks in NMR?

There are two peaks because there are two different environments for the hydrogens - in the CH₃ group and attached to the oxygen in the COOH group. They are in different places in the spectrum because they need slightly different external magnetic fields to bring them in to resonance at a particular radio frequency.
