Ab initio line-shape parameters for speed-dependent hard-collision profiles: applications to rovibrational lines of H2, D2, HD in He or H2

Abstract

Abstract We review our recent studies on the spectral line shapes of H2, including its isotopologues, self-perturbed or perturbed by helium. Line shape parameters are derived following the generalized Hess method and making use of the close-coupling formalism.
