HCl, DCl and TCl diatomic molecules in their ground state: predicting Born-Oppenheimer rovibrational spectra

Horacio Olivares-Pilón, Alexander V. Turbiner

The analytic Born-Oppenheimer (B-O) potential curve for the ground state $X^1{\Sigma }^{+}$ of the molecule (H,D,T)Cl is constructed for the whole range of internuclear distances $R \in [0,\…
