I want to simulate Pt interaction with water molecules using the following equation:Inline image 1
in which

The parameters for Pt-H and Pt-O interaction shown in the following table:

I only found Morse potential in Lammps have the similar format, does anybody know how to fit this long equation into lammps? Many Thanks!
