WebIn general, the Hamiltonian for a molecular system may be very complicated to calculate and computers are used for these purposes ( e. g. computational quantum chemistry); obviously, a computer computer needs a completely systematic method to compute the Hamiltonian (it can't certainly do that "by feeling"). Share Cite Improve this answer Follow WebA postulate of quantum mechanics is that the time evolution of any quantum system is given by the Schrödinger equation : using a suitable Hamiltonian operator Ĥ corresponding to the system. The solution is a complex -valued wavefunction ψ(r, t), a function of the 3D position vector r of the particle at time t, describing the behavior of the system.
