最近已证实在进行氧化、还原循环时,浸在电介液中的金属电极上被化学吸附着的分子的喇曼散射截面有10~5～10~6倍的增强.采用一台包括摄谱仪及低光强SIT电视摄象机在内的光学多道分析仪,可以在宽广的振动位移范围内同时而且实时地测量表面增强喇曼散射(SERS).氰化银和氰化铜络合物的SERS峰与电化学反应产物之间的关系可以通过历时约
It has recently been demonstrated that Raman scattering cross-sections of chemically adsorbed molecules on metal electrodes immersed in a dielectric fluid are enhanced by 10 to 5 to 10 to 6 times during oxidation and reduction cycles. Instrument and a low-light SIT television camera, measuring surface-enhanced Raman scattering (SERS) simultaneously and in real time over a wide range of vibration displacements. Cyanide and copper cyanide complex The relationship between the SERS peak of the material and the electrochemical reaction product can be approximated by a lapse of time
