Code used:

DUO, v. 211 (CCPForge)

Input:

Duo inputs for isotopologue 31P-32S.

31P-32S__POPS_Duo_curves.inp (contains curves as grid points)
31P-32S__POPS_Duo.inp (contains parameters)

The input files contain experimental line positions and energy terms values used to build the model. The model covers the X, B and a electronic states. The PE, DM, SO and EAM functions are represented by expansion parameters as well as on grids of points. The Duo code can be accessed via http://www.exomol.com/software/.

Zero point energy (ZPE): 

208.06 cm-1 relative to J=0.5, v=0, e
