The same 𝑉 2C(RS) (𝑟 M ) is used for all fourteen states, and it is the same in the 2023 potentials as in the 2022 ones. For 𝑉 1 P; (𝑟 M ), the 2023 potentials use the same functional form as was used in the 2022 potentials, but we improved the parameters by calculating extra points in the vicinity of the potential minima and adding these points to the diatomic data used for fitting, The SR functional form is an even-tempered Gaussian function:
