Collision Processes, Dynamic Parameters, Temperature Dependence of the Collisional Rate Coefficients of NH + OH and Deuterated Analogues on an Interpolated Potential Energy Surface

In this research, we report an interpolated potential energy surface (PES) from ab initio electronic energy of molecular fragments for NH + OH reaction and isotopic substitution. Classical trajectory simulations were performed on this surface to determine reaction probabilities and reaction cross sections for various channels. Nonlinear least squares fitting was applied to compute rate constants expressions and compute them as a function of the cross section.
