| Abstract: | The Brownian motion of a spherical particle in a generalized viscoelastic medium is discussed to obtain the complex viscosity coefficient from the photocurrent correlation function of fluorescent light radiated from the particle. This method makes it possible to measure the viscoelastic properties of a small amount of solution sample. |
