Molecular Spectroscopy

Why can molecular spectroscopy not be used to identify molecules?

[Nick Fiorentino 1E]

It can be, as, just like various atoms, various molecules absorb different types of light, just like atoms.

To elaborate on the previous answer, the differential wavelength absorption of different elements leads to different atomic spectra (that rainbow spectrum looking rectangle with black lines) which is what molecular spectroscopy deals with

Molecular spectroscopy can be used to identify molecules, since each element has a certain pattern like a fingerprint.
