The structural variation process and relation of water of amorphous Ta-IPA bulk and thin film upon heat-treatment conditions of $25^{\circ}C$ and $340^{\circ}C$ have been studied by using the radial distribution functions$ (RDF_{obs})$ estimated from the X-ray diffraction intensities, TG-DTA and Infrared spectrophotometer. The expected Ta-IPA structure was determined by comparing the $ RDF_{obs}$ with that for $RDF_{calc}$. The structure of specimens prepared by sol-gel method is basically based on the L-$Ta_2O_5$ crystal. Thin film of samples are mainly composed of octahedral Ta$O_6$and have smaller cluster than bulk samples.
