通过将捕获电子方法与负离子和正离子的研究相结合，可以获得可用于构建分子近似势能图的数据。描述了所用的实验方法，并讨论了H2O分子。负离子电流峰值分别为6.5±0.1和8.8± 0.1ev。对负离子的动能测量表明，后一个峰与第一个峰在无限分离处的相同状态有关。非弹性损耗过程与光吸收实验基本一致。一个非弹性的过程，在约3.4电子伏特的阈值进行观察。
By combining the trapped‐electron method with the study of negative ions and positive ions, it is possible to obtain data which can be used for construction of an approximate potential energy diagram of molecules. The experimental methods used are described and the H2O molecule is discussed. The negative ion current peaks at 6.5±0.1 and 8.8±0.1 ev. Kinetic energy measurements on the negative ions show that the latter peak is associated with the same state at infinite separation as the first peak. The inelastic loss processes are essentially in agreement with optical absorption experiments. An inelastic process with a threshold at about 3.4 ev is observed.
