Abstract:

The potential energy curves for the interactions between hydrogen ions H, H2 and CH4, C2H6, CF4, and C2F6 have been determined from the elastic scattering cross section measurements of Simons and coworkers. The scattering measurements indicate no minimum in the HCH4 potential curve as one might expect from the fact that mass spectrographic results indicate a proton affinity of 5 ev for CH4. Reasons are suggested why no minimum is indicated. Various crude semi-empirical schemes are suggested for correlating the potential curves for the different interaction systems. All suggested schemes are tested on the experimental results and are found to reproduce the measured potentials to within a factor of two.
