Calculation and analysis of self-broadening coefficients of water vapor lines for the 0.7–14000.0 cm$^{-1}$ spectral range

Within the framework of the semiclassical method, more than 30000 self-broadening coefficients $\gamma$ of absorption lines of water vapor have been calculated for transitions with rotational quantum numbers $J\le$ 41, $K_a\le$ 25 vibrational bands from the spectral range of 0.7–14000.0 cm$^{-1}$. The calculated and known experimental coefficients $\gamma$ are analyzed using the analytical model $\gamma{\operatorname{(sur)}}$ depending on fitted parameters. Parameters of $\gamma{\operatorname{(sur)}}$ are determined using two procedures. In the first one, parameters of $\gamma{\operatorname{(sur)}}$ are determined for individual rotational branches with a fixed value of the quantum number $K_a = 0, \dots,10$. In the second procedure, parameters of $\gamma{\operatorname{(sur)}}$ are determined from fitting of $\gamma{\operatorname{(sur)}}$ to 34635 experimental and calculated values $\gamma{\operatorname{(sur)}}$. The temperature dependence of $\gamma{\operatorname{(sur)}}$ is also determined. The obtained parameters can be used for the calculation of self-broadening coefficients of absorption lines of arbitrary vibrational bands of Н$_2$О with $J\le$ 41, $K_a\le$ 13 from the abovementioned range.
