根据朗道的电介质极化电子结合模型，解释了无限稀金属氨溶液的性质。电子被束缚在半径为3.2-3.45埃的空腔中。被俘获电子的能级通过使用单参数波函数的变分法计算。电子的溶解热和1 s → 2 p跃迁的能量的理论值与实验值是一致的，电子跃迁的能量对温度的敏感性不能仅用介电常数的温度依赖性来解释，推测电子腔半径与温度有关。
The properties of infinitely dilute metal ammonia solutions are interpreted on the basis of Landau's model for electron binding by polarization of the dielectric medium. The electrons are bound in cavities of radius 3.2–3.45 A. The energy levels of the trapped electrons are computed by the variation method using one‐parameter wave functions. It is possible to obtain theoretical values for the heat of solution of the electron and the energy of the 1s→2p transition in agreement with experimental data.The susceptibility of the energy of the electronic transition to temperature cannot be interpreted by the temperature dependence of the dielectric constant only, and it is presumed that the electron cavity radius is temperature dependent.
