The structural variation process and relation of water of amorphous Ta-IPA bulk and thin film upon heat-treatment conditions of 25℃ and 340℃ have been studied by using the radial distribution functions (RDFobs) estimated from the X-ray diffraction intensities, TG-DTA and Infrared spectrophotometer. The expected Ta-IPA structure was determined by comparing the RDFobs with that for RDFcalc. The structure of specimens prepared by sol-gel method is basically based on the L-Ta2O5 crystal. Thin film of samples are mainly composed of octahedral TaO6 and have smaller cluster than bulk samples.
