Abstract: For the collisions of atoms and molecules interacting with respect to several potential- energy surfaces, the concept of the effective potential is introduced. It gives a description of the elastic-scattering picture observed experimentally. In the present work, the possibility of using this effective interaction potential to calculate the high-temperature properties of dissociating gases is quantitatively analyzed. It is shown for the example of $H(^1\rm S)$–$\rm H(^1\rm S)$ and $\rm O(^3\rm P)$$\rm O(^3\rm P) that the error in determining the collision integrals for the temperature range 2000$$20{,}000$ Ê reaches $10%$ for the first system but is no greater than $3$$6%$ for the second.
