The correlated diffusion between particles: (1) particles on the water-air interface[1] ; (2) particles on the water-air interface[2] Experimental system The distance r scale (1) (2) Analyzing the reason of different scale of r among the three experiment, we guess there is electric dipole interaction between particles in experiment (1).
