The temporal molecular bond polarizabilities of pyridazine molecule absorbed on Ag electrode were explored from its surface enhanced Raman intensities, showing that the two nitrogen atoms are the absorption sites and the enhancement is dominated by the charge transfer mechanism. The behaviors of the charges on the skeletal bonds were demonstrated under various applied voltages, which shows the conjugation effect. This algorithm is universal for the surface systems as long as their Raman spectra are available.
