基于反应显微镜的，完整的，和时间分辨的库仑爆炸成像的振动和解离的D-2（+）分子与飞秒时间分辨率使我们能够执行相应的波包的核间距（R-）相关的傅立叶分析。计算表明，所获得的二维R相关的频谱，使波包动力学的完整表征，并直接可视化的强，超短激光脉冲场修改的分子势曲线。
Reaction Microscope-based, complete, and time-resolved Coulomb explosion imaging of vibrating and dissociating D-2(+) molecules with femtosecond time-resolution allowed us to perform an internuclear distance (R-)dependent Fourier analysis of the corresponding wave packets. Calculations demonstrate that the obtained two-dimensional R-dependent frequency spectra enable the complete characterization of the wave packet dynamics and directly visualize the field-modified molecular potential curves in intense, ultrashort laser pulses.
