The simulation of the predissociation spectrum of the Na2 23Πg∼33Πg←b3Πu (v=14,J=14) transition, observed earlier with the Perturbation Facilitated Optical–Optical Double Resonance (PFOODR) experimental method, is done within the Optimizer project with our Split-operator computational package using Padé approximations for all functions involved in the model. This simulation reproduces the experimental spectrum satisfactory well. The parameters of the model functions involved in the simulations are determined and reported. A brief description of our computational methods and programs is presented.
