Molecular bonds are computed with Hartree-Fock perturbation and related methods. They are computed in a time independent setting. So in effect there is no time evolution except for oscillations or phase changes. This is in the energy frequency domain. There is considerable research on the the

Quantum physics tells us that anything that commutes with the hamiltonian is preserved (doesn't change), the hamiltonian being the measure of energy in a system. This has led me to understand energy as a measure of change over time in a physical system. That might be obvious, except I've never
