Although over 110 chemical species have been securely identified in the interstellar and circumstellar gas, there are still many data needs for molecular astrophysics. Among these needs are new high‐resolution spectroscopic measurements of potential interstellar molecules, in particular organic radicals, metal‐bearing molecules, and molecular ions. Ab initio studies that support these experimental investigations are necessary as well. Reaction rate measurements of many ion‐molecule, neutral‐neutral, and radiative association processes are also essential.
