A Hyperfine-resolved Rotation–Vibration Line List of Ammonia (NH_{3})

Abstract

A comprehensive, hyperfine-resolved rotation–vibration line list for the ammonia molecule ({14}^NH_{3}) is presented. The line list, which considers hyperfine nuclear quadrupole coupling effects, has been computed using robust, first principles methodologies based on a highly accurate empirically refined potential energy surface. Transitions between levels with energies below 8000 cm^{-1} and total angular momentum F ≤ 14 are considered. The line list shows excellent agreement with a range of experimental data and will significantly assist future high-resolution measurements of NH3, both astronomically and in the laboratory
