Yes, spectroscopy can be used to identify molecules. Because molecules have unique structures, their absorptions and scattering of light can be used to help identify them.

I think of each atom as being its own person with its own identity, its own different characteristics, etc. Thinking of it like this, no two atoms will show the same atomic line spectrum. Just like each atom has its unique "fingerprint" for atomic spectra, the same goes for molecules, different combinations of atoms further differentiates their line spectrums.
