| Abstract |
We studied photo-induced dimerization of 4-aminobenzoic acid (4ABA) on silver surfaces in the presence of chloride anions. The dimerization took place by irradiation of the laser light and the reaction was completed within a few seconds. It is well-known that the chloride anion is a competitive adsorbate on the silver surface and can change the orientation of the probe molecules but we have not been able to confirm the orientation of the probe molecules. However, we confirmed that the dimerization did not occur in the experiment in which the chlorine ions were added. We compared these spectra with DFT calculations. The calculated spectra were in better agreement with the 4ABA spectra of the sol state than the spectra presented in the previous work. |
