... 1) Find the equations of motion of the spin operators Sx (t), Sy (t), and Sz (t) in the presence of a Hamiltonian r r r given by H egS(t) B / 2 c. (B is magnetic field, e is electric charge, is particle mass, c is the speed of light, and g is a unitless constant.) Use the fact that Sx (t), ...

... diverted here because it’s useful to see the full correct way of doing things every now and then, and Rybicki and Lightman don’t cover this. Note, by the way, that the P is not the canonical momentum (the one such that p = −i~∇), but the particle momentum; e.g., for an electromagnetic field P = p − ...

... • Observables are physical attributes of a system that can be measured in the laboratory. • In quantum physics, in the absence of a measurement, a microscopic system does not necessarily have values of its physical properties. (A particle does not “have” a position until we measure it. It has a set ...

... In solving Schrodinger’s equation Hψ=Eψ you get two pieces of information: • ψ the wavefunction – this is KEY as from it you can calculate not only the probability but any other observable quantity (e.g. dipole moment, etc.) • En -- the energy states (also called eigenvalues) ...

... In NH3 inversion the splitting E+ − E− is small (only 0.0096 kJ mol−1), and the corresponding frequency is 24 × 109 Hz which is in the microwave region. It is independent of temperature and is a consequence of the quantum nature of the protons’ motion, which results in the penetration of the vibrati ...
