The gauge independence of transition rates as opposed to the gauge invariance of the equations of motion and gauge dependence of operators and state vectors is critically examined and explicitly demonstrated, both in nonrelativistic quantum mechanics and quantum field theory. Time independent as wel

Thoorics of mngnetic propcrtiee of motecules frequently employ the "gauge invariant" L1IO's first introduced by London. The bnsis for this choice of orbit& is reviewed, at the level OC approximate SCF theory, nnd the use of inappropriate gauge factors in previous work is pointed out. The invariance
A model describing a quantum mechanical particle on a circle with minimal electromagnetic interaction with a space independent vector potential, and with a potential &M cos(.&% M ) so that it mimics the massive Schwinger model, is discussed as a prototype of mechanisms and infrared structures which
