We demonstrated how the subcycle evolution of the electric field of light can be used to control the motion of bound electrons. Results are presented for the dissociative ionization of deuterium molecules (D2 --> D+ + D), where asymmetric ejection of the ionic fragment reveals that light-driven intramolecular electronic motion before dissociation localizes the electron on one of the two D+ ions in a controlled way. The results extend subfemtosecond electron control to molecules and provide evidence of its usefulness in controlling reaction dynamics.
我们展示了光电场的亚周期演化如何可用于控制束缚电子的运动。给出了氘分子（D₂→D⁺ + D）的解离电离结果，其中离子碎片的不对称喷射表明，解离前光驱动的分子内电子运动以可控方式将电子定域在两个D⁺离子中的一个上。这些结果将亚飞秒电子控制扩展到分子，并提供了其在控制反应动力学方面有用性的证据。
