When surface‐barrier effects are not taken into account, computation of diffusion coefficients from data obtained under finite bath conditions can lead to error. A technique is given by which the most probable diffusion coefficient and the most probable dimensionless surface barrier parameter simultaneously can be estimated for diffusant uptake by solid polymeric cylinders. © 1993 John Wiley & Sons, Inc.
