二苯并[b,f][1,4]氧杂吖庚因在银胶体系中产生SERS的机理探讨

Study on the Mechanism of SERS Formation in Silver Colloid Solution Containing Dibenz(b,f) 1,4 oxaxepin

通过滴加ＮａＮＯ３、ＮａＯＨ、ＨＮＯ３、Ｈ２ＳＯ４和ＨＣｌ对银胶体系及ＣＲ（二苯并［ｂ，ｆ］［１，４］氧杂吖庚因）ＳＥＲＳ（表面增强喇曼散射）信号的影响，探讨滴加酸溶液引起银胶体系中ＣＲ瞬即产生ＳＥＲＳ的机理。

A strong SERS is produced immediatly when an acid such as HNO 3,H 2SO 4,or HCl,is added to a silver colloid solution containing dibenz(b,f) 1,4 oxaxepin(CR) The mechanism of the reaction is discussed
