Abstract: A theoretical treatment, based on a tensorial expansion of the scattering matrix, is presented for collisional
coupling between hyperfine and Stark components of molecular spectral lines. This treatment also describes the
dependence of collisional broadening of well-resolved components on F and MF quantum numbers. The case
of molecules with a large dipole moment is discussed in detail and simple selection rules are obtained for
collisional coupling by using our treatment of the relaxation matrix within a perturbative expansion of the
scattering matrix. The existing experimental results are explained.
