ExoMol line list for KCl

These line lists are suitable for temperatures relevant to exoplanetary atmospheres and cool stars (up to 3000K). Isotopologues ^23^Na^35^Cl, ^23^Na^37^Cl, ^39^K^35^Cl, ^39^K^37^Cl, ^41^K^35^Cl and ^41^K^37^Cl are considered.

Laboratory data were used to refine ab initio potential energy curves in order to compute accurate ro-vibrational energy levels. Einstein A coefficients are generated using newly determined ab initio dipole moment curves calculated using the CCSD(T) method. New Dunham Yij constants for KCl are generated by a re-analysis of a published Fourier transform infrared emission spectra.
