Optieal multichannel analyzer(OMA) combined with Raman spectrometor is applied in the study of electrochemical in-situ time -resolved Raman spectroscopy. In order to make the data acquistion of Raman and electrochemistry synchronize and to make the study more convenient, a special keystroke programm for OMA was written as a complement of the DataAcguisition(DA) mode of OMA and enhancement of the communicaiton between operator and computer.
