Abstract: | The ν3 mode of T2O, observed at 0.04 cm−1, has been analyzed. By an iterative process of fitting and assignment 210 lines were assigned; 167 of these were used in the final fitting. The standard deviation of the fit is 0.023 cm−1. The rotational constants, A, B, and C, as well as the quartic distortion constants, have been evaluated for the excited state. |
