parmed.topologyobjects.NonbondedExceptionType

class parmed.topologyobjects.NonbondedExceptionType(rmin, epsilon, chgscale=1.0, list=None)[source]

A parameter describing how the various nonbonded interactions between a particular pair of atoms behaves in a specified nonbonded exception (e.g., in 1-4 interacting terms)

Parameters
rminfloat

The combined Rmin value for this particular pair of atom types (dimension length, default units are Angstroms)

epsilonfloat

The combined well-depth value for this particular pair of atom types (dimension energy, default units are kcal/mol)

chgscalefloat, optional

The scaling factor by which to multiply the product of the charges for this pair. Default is 1.0.

listTrackedList

The list containing this nonbonded exception
