Proton Spin Decoupled

In NMR spectroscopy, it refers to a technique to simplify spectral analysis by removing the interactions (couplings) between a proton's (H-atom's) spin and the spins of adjacent atoms.

Off-Resonance Decoupled

A technique in nuclear magnetic resonance (NMR) spectroscopy used to simplify spectra by removing certain interactions.

Multiplicities

In NMR spectroscopy, refers to the splitting of a resonance into multiple peaks due to spin-spin coupling.
