In which one of the following regions of the electromagnetic spectrum will the vibrational motion of molecules give rise to absorption

A

Ultraviolet rays

B

Microwaves

C

Infrared

D

Radio waves

Text Solution

Verified by Experts

The correct Answer is:
B
Molecular spectra due to vibrational motion lie in the microwave region of EM - spectrum. Due to Kirchhoff.s law in spectroscopy the same will be absorbed.
