The following software packages are used in the calculation of ExoMol linelists and can be found at the following links within CCPForge. A recent description of the ExoMol approach to calculating large molecular line lists is given in ref .
DVR3D, a code for calculating the rotation-vibration spectra of triatomic molecules.
Duo, for calculating the energy levels and spectra of diatomic molecules with coupled electronic states.
TROVE, a code for calculating rotation-vibration spectra for general polyatomic systems
GAIN-MPI: Gpu Accelerated INtensities is a standalone code used to accelerate the calculation of line strengths from TROVE wavefunctions by utilizing MPI and graphics processing units (GPUs).
