Solution:

Molecular spectra occurs due to vibrational motion lie in the microwave region of EM-spectrum due to Kirchoff's law in spectroscopy the same will be absorbed. Kirchoff's law in-spectroscopy explains the spectrum of an object is the radiation in the intensity of its radiation at different wavelengths
