Well, you got us here....

Explanation:

In general, we can define spectroscopy as the interaction of the electromagnetic spectrum with MATTER.... And spectroscopy today is a VERY broad church that encompasses a multitude of techniques and disciplines.

And in general, a component of the electromagnetic spectrum, a photon or what have you, interacts with a molecule, or atom, or with a functional group. And this is thus an example of qualitative analysis, i.e. it tells us what we got. Most spectroscopies are ALSO quantitative; the size of the signal is proportional to the number of absorbing species, and thus spectroscopy allows #"quantitative"# as well as #"qualitative analysis"#.

Anyway, if there is something more specific, you will have to ask the question,
