从量子力学的观点讨论了与电子跃迁有关的核运动问题。看来海森堡的不确定性原理给出了早期基于弗兰克假设的方法的不精确性的线索，因为它的严格应用要求违反该原理。由于物质的波动性，本文预言了一种全新的带谱类型的存在，并建议将2476-2482 Au的瑞利汞带解释为这种类型。最后，它表明，虽然弗兰克的假设也是真实的电子跳跃原子，但微不足道的兴趣，因为它的不精确性是更大的电子比重核。
The question of nuclear motions associated with electron transitions is discussed from the standpoint of quantum mechanics. It appears that Heisenberg's indetermination principle gives the clue to the inexactness of the earlier method based on Franck's postulate since its strict application calls for a violation of the principle. The existence of an entirely new type of band spectrum due to the wave nature of matter is predicted and the interpretation of Rayleigh's mercury band at 2476-2482 AU as of this type is suggested. Finally it is shown that while Franck's postulate is also true for electron jumps in atoms, it is of but trivial interest because its inexactness is much greater for the electrons than for heavy nuclei.
