I want to set Dihedral in force filed parameter file
I don't know what should I set for n:multiplicity
it is described as 2S+1
namd user guide says "The “multiplicity” n is typically 1, 2, or 3, although for a
small number of cases two or three terms with different values of n are provided for
the same atom types."
I have a case two or three terms with different values of n are exist:
SI O SI O -0.0100 ?? 180.00
SI O SI O -0.2350 ?? 180.00
does anyone know what should I do?
