    "abstract": "The accuracy of calculation of spectral line shapes in one-dimensional\napproximation is studied analytically in several limiting cases for arbitrary\ncollision kernel and numerically in the rigid spheres model. It is shown that\nthe deviation of the line profile is maximal in the center of the line in case\nof large perturber mass and intermediate values of collision frequency. For\nmoderate masses of buffer molecules the error of one-dimensional approximation\nis found not to exceed 5%.",
