飞秒激光研究分子的振动和转动周士康（中科院安徽光机所激光光谱学开放室，合肥，２３００３１）一切复杂的分子运动都是以分子的振动、转动为基础的，分子的振动、转动是整个分子光谱的出发点。但是，用光谱来研究分子运动的几十年来，人们都是从分子的光谱来ｖ天推”出... Femtosecond Laser Studies Molecular Vibration and Rotation Zhou Shikang (Laboratory of Laser Spectroscopy, Chinese Academy of Sciences, Hefei, 230031) All complex molecular motions are based on the vibration and rotation of molecules. The molecular vibration and rotation are the whole The starting point of molecular spectroscopy. However, in the decades that spectroscopy has been used to study molecular motion, people have been pushing “out of the spectrum of molecules” for days ...
