This conference is an international forum to discuss fundamental and applied research associated with the formation of spectral line profiles. It includes research involving line profiles observed in absorption, emission, and scattering by laboratory and astrophysical sources. The conference brings together specialists from many diverse fields to discuss common aspects of line shape theory and experiments. Areas covered in the conference included: laser-produced plasmas, magnetically confined plasmas, stellar atmospheres, molecular and atomic systems, high-resolution spectroscopic applications and measurements, collision-induced effects, and ultracold regimes. Papers on experiments, theory, and applications are included in this volume.
