In introductory chemistry textbooks [0] a diatomic example is mostly used as an illustration, for &gt;2 atoms usually only the ground state is considered. This is because (1) in a diatomic setting the vibrational degree of freedom in…</p><p><a href="https://hackerpaper.kaipfister.de/p/2211.07319/">Paper and discussion history</a>.
