We present ab initio calculations of spectral line shapes for foreign-perturbed hydrogen molecule and its validation against experimental data. Two collisional effects substantially influencing the shape of optical resonance have to be considered: the phase- or state-changing collisions and the velocity-changing collisions. We calculate these two contributions originating from the interaction potential.
