提出了独立可调中红外脉冲的双频二维红外外差光子回波实验。利用3 μm、3 μm和6 μm脉冲序列，通过观察NH和CO的相互作用，表征了NH和CO之间的分子间氢键。确定的结构和动力参数包括模态耦合、角约束和频率分布的相关因子。
Dual-frequency 2D IR heterodyned photon echo experiments with independently tunable mid-IR pulses are presented. Intermolecular hydrogen bonding between NH and CO groups is characterized via observation of interaction of the NH and CO vibrational modes using a sequence of 3, 3, and 6 μm pulses. Structural and dynamical parameters determined include the mode coupling, angular constraints, and a correlation factor for the frequency distributions.
