Infrared (IR) and Raman Spectroscopy (RS) depend on vibration or rotation of bonded atoms. Nuclear Magnetic and Electric Quadrupole Resonance (NMR, NQR) depend on transitions between quantized energy levels for interactions of the magnetic dipole and electric quadrupole of an atomic nucleus with ...
红外光谱（InfraredSpectroscopy,简称IR）拉曼光谱（Raman）分子光谱 两者得到的信息可以互补。在十九世纪初就发现了红外线,到1892年有人利用岩盐棱镜和测热幅射计(电阻温度计)测定了20多种有机化合物的红外光谱。1905年科伯伦茨发表了128种有机和无机化合物的红外光谱，红外光谱与分子结构间的特定联系才被确认。到1930...
Paralleling the evolution of Fourier Transform Infrared Spectroscopy during the 1960's and 1970's there have been rapid developments in the area of Raman spectroscopy. The laser serves only in a secondary role for FT-IR spectroscopy, but as a source for excitation it has greatly revolutionized co...
