狄拉克为简并拉格朗日描述的系统的正则量子化所设计的程序被用来构造与电磁场相互作用的分子的哈密顿量。得到的哈密顿量用规范不变场强和分子的电、磁多极矩表示。介绍了库仑量规，但也可以采用其他量规条件。最后，给出了可用于生成多极哈密顿量的酉变换的物理解释。
The procedure devised by Dirac for the canonical quantization of systems described by degenerate lagrangians is used to construct the hamiltonian for molecules interacting with the electromagnetic field. The hamiltonian obtained is expressed in terms of the gauge invariant field strengths and the electric and magnetic multipole moments of the molecules. The Coulomb gauge is introduced but other gauge conditions could be used. Finally, a physical interpretation of the unitary transformation that may be used to generate the multipole hamiltonian is given.
