Abstract : Reexamination of current semiempirical methods for computing Einstein coefficients for diatomic molecules has resulted in the development of a new technique for predicting infrared transition probabilities. The method uses a nonlinear transformation of existing polynomial dipole expressions with the subsequent application of appropriate boundary conditions to arrive at improved dipole curves. The transition probabilities predicted for HF are found to be in excellent agreement with the available experimental data. With slight variations, the method is applied to DF, HCl, DCl, OH, and OD with comparable success. Preliminary results are given for the transition probabilities for the CO and NO molecules.
