Potential Model for Binding Energy of First and Second Row Diatomic Molecules

The exact knowledge of binding energy in atoms and molecules of diatomic molecules have its crucial role in its spectroscopic study. On the basis of which it is possible to predict various spectroscopic properties of the molecules. Although the binding energy in alkali halides may be fairly well described in terms of e2/r, but it is observed that for all the hydrides under present study e2/r is less than the magnitude of the total experimental potential energy, thus for selected samples the potential models are established by considering the ionic charges as +Ze and -Ze. We have proposed a new potential based on and different from existing GP, BM and other Potential fuctions. And compared the results obtained for the binding energy of the samples under study. It is found that the new potential model L5 has been proved good for the various molecules under the present study. These can be arranged in order of applicability to model L5 as BH, HF, LiH, AlH, BeH, NaH , MgH , CH, SiH, CH, SH, NH, PH and HCl. Thus the validity of proposed model is established among the existing Born – Mayer, Gaussian and Logarithmic Models
