  1. 2. 2 光谱分析 • 当光照射到物体上时,电磁波的电矢量就会与被照射物体的原子和分子发生相互作用引起,利用这种相互作用引起被照物体内分子运动状态发生变化,并产生特征能态之间的跃迁进行分析的方法。 • E=hν=hc/λ • ύ=1/λ • 光谱分析的类型: • 吸收光谱, IR、UV • 发射光谱, FS • 散射光谱, Ramn

  2. IR:500~4000cm-1,大多数化合物的化学键振动能级的跃迁发生在这一区域,因此我们主要研究中红外区域的吸收光谱,即分子的振动光谱。IR:500~4000cm-1,大多数化合物的化学键振动能级的跃迁发生在这一区域,因此我们主要研究中红外区域的吸收光谱,即分子的振动光谱。
