Our numerical calculations using a very simple program written in Mathematica is compared with other calculations. We show that our results have a similar accuracy as the calculations performed with more sophisticated methods. We discuss the extension of our method to include non-Condon effects in the calculation.LaTeX, 27 pages, 7 Tables, 1 figureChemical PhysicsComputational Physicstext
