1.

measuring absorption of ultraviolet or visible light.

Infrared (IR) Spectroscopy: Provides insights into molecular vibrations, helping

2.

identify functional groups within molecules.

Nuclear Magnetic Resonance (NMR) Spectroscopy: A powerful tool to

3.

elucidate molecular structure and dynamics by observing magnetic properties of

atomic nuclei.
