Abstract

High-order harmonic generation (HHG) from nonadiabatically aligned molecules has been demonstrated to have new abilities to probe molecular dynamics and structures with femtosecond (fs) temporal resolutions [1–4]. In the recent study of HHG from coherently rotating molecules, the present authors have shown that HHG properties strongly depend on the degree of molecular alignment, and a low rotational temperature Trot and resulting high degree of alignment is strongly desired in the HHG experiment to retrieve the image of electronic distribution or orbital structure in a molecule [3].
利用定位相关的高次谐波产生探测分子结构
非绝热排列分子的高次谐波产生(HHG)已被证明具有飞秒(fs)时间分辨率探测分子动力学和结构的新能力[1-4]。在最近对相干旋转分子HHG的研究中,本文作者已经表明,HHG的性质强烈依赖于分子的排列程度,并且在HHG实验中强烈需要低旋转温度Trot和由此产生的高排列程度,以检索分子中的电子分布或轨道结构的图像[3]。
