No, PMR (Pulse Mass Ratio) and NMR (Nuclear Magnetic Resonance) are not the same. PMR is a technique used in mass spectrometry, while NMR is a technique used in spectroscopy to study the magnetic properties of atomic nuclei. Both techniques are valuable in analytical chemistry but serve different purposes.

NMR stands for Nuclear Magnetic Resonance. It's an analytical/spectrographic technique based on the Zeeman effect.
