Electron Transitions

What is the difference between atomic spectroscopy and molecular spectroscopy?

Someone on another post said this and it helped me hope it does the same!
"Atomic spectra are the transitions of electrons between electronic energy levels in isolated atoms. They are affected by interactions of the transitioning electrons with the nuclei spins and with the other electrons in the atom.

Molecular spectra involve transitions in molecules with two or more atoms (either the same or different). Since the valence electrons are now in different orbitals from the atomic orbitals and the orbital structure has changed the electronic transitions are different."

I also read this which may help "atomic spectroscopy refers to the study of the electromagnetic radiation absorbed and emitted by atoms whereas the molecular spectroscopy refers to the study of the electromagnetic radiation absorbed and emitted by molecules"
