光谱是物质的特性之一,每一物质都有其独特的光谱。物质不同,光谱亦异。分子光谱研究紫外、可见、红外光域的电磁波与物质的相互作用。研究分子的振动和转动能级跃迁的主要方法是红外吸收光谱和拉曼散射光谱;研究分子的电子能级跃迁的是电子光谱。我国自开始分子光谱工作迄今已有五十余年的历史。下面就我国建国以前和以后两个时期来分别概述我国在分子光谱方面的一些主要工作和成就。
Spectroscopy is one of the characteristics of matter, each matter has its own unique spectrum. Different substances, the spectrum is different. Molecular spectroscopy UV, visible, infrared light field of electromagnetic waves and material interaction. The main methods to study molecular vibrational and rotational energy level transitions are infrared absorption spectroscopy and Raman scattering spectroscopy. It is electron spectroscopy to study electronic energy level transition of molecules. Our country has started more than fifty years of molecular spectroscopy work so far. Hereunder, we briefly outline some major tasks and achievements of our country in molecular spectroscopy before and after the founding of our nation.
