✦ Synopsis

A method based upon elementary quantum mechanics for constructing a path integral representation or spin amplitudes is described. A path integral representation obtained earlier for the unitary rotation matrices is rederived. In this system, the appropriate set of classical canonical variables and their quantum counterparts are identified. It is suggested how this method can be extended to more general systems by using the three-dimensional unitary group as another example.
