The ro-vibrational transitions of NaH are crucially needed for the control of photo-association processes resulting from its formation and for accurately modeling the NaH abundance in space. In this work, we constructed new PESs of the NaH-He system.

International audience; In this paper, we focus on the determination of the rotational excitation rate coefficients of the first observed molecule containing noble gas 36ArH+ isotope by He. Hence, we present the first potential energy surface (PES) o
