We discuss the sensitivity of the pressure broadening cross-sections to the choice and properties of a potential energy surface. We compare the dihydrogen pressure broadening cross-sections for isotropic Raman and IR acetylene lines. Because of their particular interest we also compare the H2 and D2 broadening of acetylene lines and their resp. ortho and para contributions to the total pressure broadening cross-sections.
