Conceptual Question [ENDORSED]

[ariellasarkissian_3H]

Can someone explain the concept behind the question of the study sheet... "With respect to electron transitions that give rise to a UV or visible spectrum: understand the difference between electronic transitions in atomic orbitals (atomic spectroscopy) and electronic transitions in molecular orbitals (molecular spectroscopy)." Thank you!

Same concepts I used in class to discuss atomic spectra (electronic transitions between atomic orbitals) apply to molecular spectra (electronic transitions between molecular orbitals).
In Chem 14BL you will hear more about UV spectra in molecules.
