Using the genetic algorithm, we fit the potential energy curves of the $\\rm A^1\\Sigma^+$ state and the $\\rm b^3\\Pi$ state into point-wise form. We then fit these point-wise potentials along with the spin-orbit coupling into expanded Morse oscillator functional form and optimise analytical parameters based on the experimental data.
