Atomic vs Molecular Spectroscopy

Postby 405335722 » Tue Nov 05, 2019 3:35 pm

what is the difference between electronic transitions in atomic orbitals (atomic spectroscopy) and electronic transitions in molecular orbitals (molecular spectroscopy)?

Both deal with absorption of light at different energy levels and both can yield a line spectrum. Atomic spectra only deal with the energy transition of a valence electron in that atom, which molecular spectra deal with the different valence electrons of the different atoms in the molecule. In both, electrons are being excited to higher energy states, but the transitions are different.
