Astrochemistry is the study of the nature, behavior, and history of molecules and materials in various astronomical environments. Theoretical chemistry contributes to understanding astrochemical processes at the molecular level in a number of ways:

• Quantum chemical calculations of structure, chemistry, and spectroscopic properties
• Kinetic theory of chemical rates and collision behavior
• Molecular dynamics or Monte Carlo simulations of extended model systems

• To improve awareness among the full astrochemistry community of who contributes to this area and where their interests lie
• To promote communication and collaboration between molecular theorists and experimentalists, modelers, and astronomers
• To organize efforts to enhance the impact of molecular theorists on the full astrochemistry community
