红外光谱:当样品受到频率连续变化的红外光照射时,分子吸收某些频率的辐射,并由其振动运动或转动运动引起偶极矩的净变化,产生的分子振动和转动能级从基态到激发态的跃迁,使相应于这些吸收区域的透射光强度减弱,将测得的吸收强度对入射光的波长或波数做图,就是红外光谱。而利用材料对红外光区辐射的选择性吸收进行结构分析、定性和定量方法,称之为红外吸收光谱法。


拉曼光谱:上海11选5开奖结果当光照射到物质使,光子与分子内的电子碰撞,发生非弹性碰撞,光子就有一部分能量传递给电子,此时散射光的频率就不等于入射光的频率,这种散射被称为拉曼散射,所产生的光谱被称为拉曼光谱。据此可以通过测定散射光相对于入射光频率的变化来获取分子内部结构信息,这就是拉曼光谱分析法。
