摘要：

A method for measuring diffusion using a simple ATR device is demonstrated using water swollen cellophane film. The diffusion coefficient (D = 0.56 × 10−9 m2 s−1) was comparable to previously published results for similar samples, but significantly different from recent measurements by NMR imaging on identical samples. An explanation is proposed based on cellophane morphology and diffusion through pores.
