我们提出了一个完整的量子力学计算的谐波光谱振动分子。通过考虑H2 +分子的振动运动，我们表明，振动能级的频率信息可以提取的谐波产量。此外，还研究了激光诱导动力学，发现谐波的发射效率与随时间变化的核间距有关。我们证明了由泵浦或探测脉冲引发的振动动力学可以同时由高次谐波产生过程来研究。
We present a fully quantum-mechanical calculation of the harmonic spectra from vibrating molecules. By considering H2 + molecules prepared in vibrating motion, we show that the frequency information of the vibrational levels can be extracted from the harmonic yields. The laser-induced dynamics is studied in addition and it is found that the emission efficiency of the harmonics is correlated with the time-varying internuclear separation. We demonstrate that the vibrational dynamics initiated by the pump or by the probe pulse can be investigated simultaneously by the high-order harmonic generation processes.
