[gmx-users] RB-coefficients of dihedral angles of triethyl phosphate itp

[Rana Ali]

Dear Sir
I have downloaded the itp file of triethyl phospathe and have run it
successfully.

Could you please help me how to find out the RB coefficients (c0, c1, c2,
c3, c4, c5) for dihedral angle given in the itp file  which is given below.
