The main purpose of Commission 14 is to foster interactions between the astronomical community and those conducting research on atoms, molecules and solid state particles. One way the Commission accomplishes this goal is through triennial compilations on recent relevant research in atomic, molecular and solid state physics, as well as related chemical fields. The most recent compilations appear in the following set of WG Triennial Reports, which were produced by members of the Working Groups and the Organizing Committee of Commission 14. Before presenting the Reports, we highlight the meetings supported by the Commission.
