An original infinite order method to calculate line broadening is proposed using projection operator algebra and the Linked Cluster Theorem. The S matrix elements are calculated iteratively at any order of perturbation theory. A first application to the O→2H2–Ar rotational line is performed. [ABSTRACT FROM AUTHOR]
