SUMMARY
The discussion centers on the conservation of total angular momentum in the hydrogen ion molecule H₂⁺, as presented in Wolfgang Demtroder's book "Molecular Physics." The claim that total angular momentum is a constant quantum number is contested, with the argument that the nuclear potential in H₂⁺ is not spherically symmetric, thus violating conservation. Instead, it is noted that while total angular momentum is not conserved, quantities related to the axis of symmetry are conserved, aligning with Noether's theorem.
