The 693 vibration-rotation line intensities of the H2 18O molecule first hexad interacting vibrational states have been fitted for determining the parameters of the transformed dipole moment. The experimental data (J.-P. Chevillard, J.-Y. Mandin, C. Camy-Peyret, and J.-M. Flaud, Canad. J. Phys.64, 746-761 (1986)) and the rotational constants (O. N. Ulenikov and A. S. Zhilyakov, J. Mol. Spectrosc.133 (1989)) were used as the initial data. The parameters obtained from the fitting reproduce the experimental line intensities with an average accuracy of 6-8%.
