H2–H collision-induced absorption spectra are computed for temperatures from 1000 K to 2500 K and frequencies from 100 cm-1 to 10 000 cm-1. The calculations are quantum mechanical and the isotropic potential approximation has been applied. The computed absorption in the fundamental band agrees roughly with the one determined by Patch (1974). However, the absorption in the translational band, which has not been obtained before, is significantly stronger than in the fundamental band.
