difference between atomic spectra and spectroscopy

[Natalie Keung 1D]

Hello!

Can anyone please give a short description of differences of these two concepts? I am struggling with differentiating them.

Atomic spectra (spectroscopy) concern only the properties of atoms, whereas molecular spectroscopy concerns the molecules which are infinitely more numerous. With atomic spectroscopy, you can find the nature and the amounts of a given element in your sample. Molecular spectroscopy concerns all the interaction of electromagnetic waves with matter and gives you much more advice than atomic spectroscopy especially about chemical functions, the structure of matter. Hope this helps!
