Definitions:

Doublet

A pair of closely spaced lines or peaks observed in spectroscopy or other forms of analysis, indicating two related quantum states.

Singlet

In spectroscopy, a singlet represents a state in which all the electron spins are paired, leading to no magnetic spin multiplicity in the atomic or molecular orbital.

Proton Spin Decoupled

A nuclear magnetic resonance technique where the interaction between hydrogen nuclei and neighboring nuclei is removed to simplify the spectrum.

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.
