Abstract Speckle movements are discovered in the investigation of a platinum-hydrogen system in 1N HClO4. The speckle pattern of the light scattered off by a platinum-electrode surface is displaced laterally as a whole as a function of the electrode potential. The derivative of the photocurrent profile corresponding to the speckle displacement has four peaks in the so-called hydrogen region of the electrode potential. Three of these peaks have a certain correlation with the electrochemical aging effect which is attributed to hydrogen adsorbed on to the electrode surface. The feasibility of using this effect for in situ investigations of the metal-solution interface is pointed out.
