Fourier transform infrared spectroscopy and laser Raman spectroscopy were applied to reveal the reaction processes and products in the T2O-CO2 system balanced by nitrogen gas. The IR intensities and Raman activities of the products that might be created by beta induced reactions were calculated using Gaussian98 and the peaks of Raman and FT-IR were determined. It was found that the T2O and CO2 are so stable that the reaction products were not found in this study. Mass spectroscopy was also applied at the end of the experiment and it became clear that most of the condensed matter is tritiated water and the other substances by beta-decay reaction were not confirmed clearly.
