51118 is the conversion factor to convert md rad"1 molecule"1 to kcal deg"1 A"1. 3 (16) Bend-Bend Interaction The MM3 bend-bend interaction connects two adjacent angles with the same common central atom. The bend-bend constant is a geometric mean of the two individual angles, and it is a pre-determined value which depends only on the atom type arrangement of the angle. 02191418. The two terms A0ijk and A0ijm represent the differences in altered and natural bond angles in units of degrees. 4 (17) Torsion-Stretch Interaction The bond length is a function of its dihedral angle, which can, in part, be described by Equation 4.
