Several of NASA missions (TESS, JWST, WFIRST, etc.) and mission concepts(LUVOIR, HabEx, and OST) emphasize the exploration and characterization ofexoplanets, and the study of the interstellar medium. We anticipate that a muchbroader set of chemical environments exists on exoplanets, necessitating datafrom a correspondingly broader set of chemical reactions. Similarly, theconditions that exist in astrophysical environments are very different fromthose traditionally probed in laboratory chemical kinetics studies. These areareas where quantum mechanical theory, applied to important reactions viawell-validated chemical kinetics models, can fill a critical knowledge gap.Quantum chemical calculations are also introduced to study interior of planets,photochemical escape, and many critical chemical pathways (e.g. prebioticenvironments, contaminations, etc.) After years of development of the relevantquantum chemical theories and significant advances in computational power,quantum chemical simulations have currently matured enough to describe realsystems with an accuracy that competes with experiments. These approaches,therefore, have become the best possible alternative in many circumstanceswhere performing experiments is too difficult, too expensive, or too dangerous,or simply not possible. In this white paper, several existing quantum chemicalstudies supporting exoplanetary science, planetary astronomy, and astrophysicsare described, and the potential positive impacts of improved models associatedwith scientific goals of missions are addressed. In the end, a fewrecommendations from the scientific community to strengthen related researchefforts at NASA are provided.
