Definitions:

Off-Resonance Decoupled

A technique in NMR spectroscopy used to simplify the spectrum by selectively removing couplings between nuclei.

Proton Spin Decoupled

A nuclear magnetic resonance (NMR) technique used to simplify spectra by removing proton-proton coupling interactions.

Down Field

In NMR spectroscopy, referring to shifts in resonance frequency towards lower magnetic field strengths, often indicating an electron-withdrawing environment.

Proton Spin Decoupled

A technique in NMR spectroscopy where the interactions between proton spins are removed or decoupled, simplifying the spectrum and making it easier to interpret.
