Abstract:Tritium is a radioactive isotope of hydrogen. Tritium released into natural enviroment is said to be converted into mostly HTO. The detection of HTO is important from the viewpoint of basic science as well as its radioactivity. Spectroscopy is a good tool for detection, however, high-resolution spectroscopy studies are still limited. The microwave study were carried out and the molecular constants of the ground state were determined. $\footnote{P.~Helminger, F. C. De Lucia, W. Gordy, P. A. Staats and H. W. Morgan, \textit{Phys. Rev. A} \underline{\textbf{10}}, 1072 (1974).}$ All fundamental $\nu$$_1$, $\nu$$_2$ and the $\nu$$_3$ bands of HTO were reported. \footnote{S. D. Cope, D. K. Russell, H. A. Fry, L. H. Jones, and J. E. Barefield, \textit{J. Mol. Spectrosc.} \underline{\textbf{127}}, 464 (1988).} $^,$\footnote{P. P. Cherrier, P. H. Beckwith, and J. Reid, \textit{J. Mol.

Phys.} \underline{\textbf{3}}, 1945 (2012).} At 1.38 micron region, overtone and combination bands are expected. In this study, we prepared a new double wall cell for safe handling of highly concentrated tritiated water and carried out the near-infrared measurement. More than 100 transitions were observed and most of them were assigned to belong to the 2$\nu$$_3$ band based on the previous quantum chemical calculations. $\footnote{M. J. Down, J. Tennyson, M. Hara, Y. Hatano, and K. Kobayashi, \textit{J. Mol. Spectrosc.} \underline{\textbf{289}}, 35 (2013).}$ We will report the current status of the analysis.
