Abstract
The advantages of photon correlation spectroscopy as applied to an investigation of the hydrodynamic properties of liquid-air interfaces are discussed. Because of instrumental resolution, experimentally determined correlation functions have damping coefficients which yield values for liquid viscosity greater than accepted values. The discrepancy is resolved and an analytic expression developed to account for the apparatus and to exactly fit the observed correlation functions.Keywords
