The peculiarities of broadening of spectral lines of symmetric top molecules that are related to thedouble degeneracy of JK levels at K ? 0 are considered. It is shown that, irrespective of the potential barrierheight for the inversion vibration, transitions between such levels should be considered as doublets whose componentsare coupled with each other by the collision-induced spectral exchange. The shape of the doublet isdescribed by the well-known Ben-Reuven formula, and, in this case of molecules with a high potential barrierfor the inversion vibration, is a dispersion contour with a halfwidth equal to the difference between the halfwidthof the component of the doublet and the cross-relaxation parameter.
