TorsionAngleContrib() [2/2]

ForceFields::MMFF::TorsionAngleContrib::TorsionAngleContrib	(	ForceField *	owner,
		unsigned int	idx1,
		unsigned int	idx2,
		unsigned int	idx3,
		unsigned int	idx4,
		const MMFFTor *	mmffTorParams
	)

Constructor.

The torsion is between atom1 - atom2 - atom3 - atom4 (i.e the angle between bond atom1-atom2 and bond atom3-atom4 while looking down bond atom2-atom3)

Parameters

owner	pointer to the owning ForceField
idx1	index of atom1 in the ForceField's positions
idx2	index of atom2 in the ForceField's positions
idx3	index of atom3 in the ForceField's positions
idx4	index of atom4 in the ForceField's positions
torsionType	MMFF type of the torsional bond between atoms 2 and 3
