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 $F\le 14$ are considered. The line list shows excellent agreement with a range of experimental data and will significantly assist future high-resolution measurements of NH${}_3$, both astronomically and in the laboratory.
