Scientific paper

Partition functions for H3(+) and H2D(+) are calculated by explicit summation of ab initio rotation-vibration energy levels for temperatures up to 2800 K. Estimates of the errors are given. A previously proposed high temperature approximation to the nuclear spin statistics of H3(+) is tested and found to be reliable. Equilibrium constants are given as a function of temperature for the main H3(+)-forming reaction H2 + H2(+) - H3(+) + H and reactions responsible for deuterium fractionation H3(+) + D - H2D(+) + H and H3(+) + HD - H2D(+) + H2. Comparisons are made with data previously used for modelling.
