Definitions:

NMR

Nuclear magnetic resonance, a spectroscopic technique used to observe local magnetic fields around atomic nuclei, providing detailed information about the structure, dynamics, reaction state, and chemical environment of molecules.

IR

Infrared spectroscopy, a technique used in chemistry to identify compounds and investigate molecular structure by analyzing the vibration of bonds under infrared light.

Triplet

A term in quantum mechanics referring to a system (often an electron) that exists in three possible states with the same energy, typically in the context of spin states.

NMR

Nuclear Magnetic Resonance, a technique that exploits the magnetic properties of certain atomic nuclei to determine physical and chemical properties of atoms or the molecules in which they are contained.
