Definitions:

Triplet

In chemistry, a molecular entity with three similar elements or functional groups in its structure or a magnetic quantum state distinguished by three levels.

Doublet

A pattern observed in NMR spectroscopy, indicating two adjacent hydrogen atoms influencing the resonance of another hydrogen or group.

Off-Resonance Decoupled

A technique in NMR spectroscopy where decoupling is applied at a frequency offset from the resonance frequency of the nucleus of interest to simplify spectra.

Multiplicities

In nuclear magnetic resonance (NMR) spectroscopy, multiplicities refer to the splitting pattern of a signal, indicating the number of nearby hydrogens (or other nuclei) interacting with the observed nucleus.
