§Hydrogen Bond Potentials

Specialized potentials for hydrogen bonding interactions.

§Available Types

TypeDescriptionFormula
DreidDREIDING 12-10D0 * (5*(R0/R)^12 - 6*(R0/R)^10) * cos^N(theta)
LjCosLJ with angular4*eps*((sigma/r)^12 - (sigma/r)^6) * cos^N(theta)

Both use const generic N for compile-time optimization of the angular exponent.

§Notes

These are “explicit” H-bond potentials. Many force fields treat H-bonds implicitly through standard electrostatics and vdW.

Structs§
