Definitions:

Resamples Without Replacement

Resampling without replacement involves selecting subsets of data where each sample is only chosen once for inclusion in any subset.

Proton Spin Decoupled

A technique in NMR spectroscopy where the coupling between protons is removed to simplify the spectrum.

Distinct Quartets

In NMR spectroscopy, a pattern indicating a group of hydrogen atoms coupled to three other hydrogens, resulting in four equally spaced peaks.

Off-Resonance Decoupled

In NMR spectroscopy, a technique used to simplify complex spectra by decoupling specific nuclei from the observed spin-spin interactions.
