Collision induced spectra contribute to a major part of the opacity in the outer planets, which
are composed of non-polar species like H
, and He. Recently a new interest for collision
induced
spectra has appeared with the need of opacities for the modelling of cool and dense stars:
white dwarfs, brown dwarfs, etc.
Accurate calculations of H
-H
(72), H
-He (73), CO
-CO
(74), N
-N
(75), and CH
-H
(69)
pairs have been carried out. The accuracy of the results depends directly
on the quality of the intermolecular potentials.
