Abstract
Dunham coefficients Ymj of the H36Cl molecule are calculated using previously determined mass-independent spectroscopic parameters Umj , D mjA and D mjB . Pure rotational and vibration-rotation transitions of the (1-0), (2-0) and (3-0) bands are presented up to J max = 25 for the first time. The comparisons of calculated line positions to observed ones for the fundamental and first overtone bands are given. The RKR potential of the H36Cl molecule is retrieved.
