论文摘要
在化学，生物学和材料科学中，随着飞秒激光器的出现，获得原子间相互作用及其动力学进化的能力已成为可能。特别是，通过光学（UV-Visible-IR）光谱镜观察振动波数据包已成为一项重大成就，因为它可以跟踪系统内的核运动。但是，光谱镜仅检测原子间振动对全球电子表面的影响。短波长辐射的新型可调，脉冲和极化来源，例如X射线无电子激光器，可以克服这种局限性，从而使化学限制，并且在生物化学，对映体选择性中起主要重要性。可以通过考虑属于不同分子部分的原子的化学位移来补充这种选择性
In chemistry, biology and materials science, the ability to access interatomic interactions and their dynamical evolution has become possible with the advent of femtosecond lasers. In particular, the observation of vibrational wave packets via optical (UV-visible-IR) spectroscopies has been a major achievement as it can track the motion of nuclei within the system. However, optical spectroscopies only detect the effect of the interatomic vibrations on the global electronic surfaces. New tuneable, pulsed and polarized sources of short-wavelength radiation, such as X-Ray Free electron lasers, can overcome this limitation, allowing for chemical and, of primary importance in biochemistry, enantiomeric selectivity. This selectivity may be complemented by taking into account the chemical shifts of atoms belonging to different molecular moieties
