摘要
Based on a quantum-mechanical expression for the kernel of the collision integral and the dispersion intermolecular interaction potential, we have calculated the line profiles in which the collisions with scattering through large and classical small angles as well as the diffraction scattering of molecules have been simultaneously taken into account. By comparing the calculated profiles with those in the models of hard velocity-changing collisions, we show that disregarding soft collisions leads to a noticeably sharper line shape. In an effort to quantitatively process the spectra, we have parameterized the calculated profiles and obtained their algebraic approximation.
