Abstract:

Rotational-vibrational constants for (006) and (007) vibrational states of the HDO molecule are determined by use of the least squares fitting to experimental rotation-vibration energy levels. All the known rotational constants, as well as integrated band intensities are approximated using the Pade method, and spectroscopic constants of nv₃-type bands are predicted for n = 8…15. The calculations showed that the rotational A constant decreases strongly, almost two times, due to the rotational-vibrational interaction.
