摘要: Reflectance measurements were obtained in situ of methylene blue films on a stress-annealed pyrolytic graphite electrode. The optical response the charging region double layer was observed for p polarization form small bipolar band at 690 nm, red shifted 0.08 eV with respect to monomer species solution. intensity found depend linearly modulation amplitude. On contrary, only tiny changes shape and frequency bias potential detected. average orientation adsorbed dye is discussed together role Stark effect as likely source.
