Solution
The correct option is D IR Raman Spectroscopy is a spectrocopy technique used to observe vibrational, rotational, and other low-frequency modes in a system.Raman spectroscopy is commonly used in chemistry to provide a fingerprint by which molecules can be identified.
Infrared beams are used for illumination of the molecules and the dispersed light if collected on the detector.
