Collision-induced dissociation experiments on the Ag+-phenylalanine complex using several collision energies were shown to yield ten different fragment ions. Unambiguous assignment of these fragment ions were made by careful analysis of deuterium labeling experiments. The losses of H2O, CO, CO2, and AgH were commonly observed; also encountered were the losses of H2, Ag, and H. Deuterium labeling experiments and density functional calculations have been employed to probe fragmentation mechanisms that account for all experimental results.

Ag +-苯丙氨酸络合物的气相裂解：阳离子-π相互作用和自由基阳离子的形成。

使用几种碰撞能在Ag +-苯丙氨酸络合物上进行的碰撞诱导解离实验显示，可产生十种不同的碎片离子。这些碎片离子的明确分配是通过对氘标记实验的仔细分析来完成的。通常观察到H2O，CO，CO2和AgH的损失。还遇到了H2，Ag和H的损失。氘标记实验和密度泛函计算已被用来探测解释所有实验结果的碎裂机理。
