-# nb3b/harmonic (nonbonded 3-body harmonic) parameters for various elements
-#
-# multiple entries can be added to this file, LAMMPS reads the ones it needs
-#
-# these entries are in LAMMPS "real" units:
-#   k [kcal/mol/rad^2], theta_0 [degrees], cutoff [Angstroms]
-#
-# format of a single entry (one or more lines):
-#   element 1 (central atom), element 2, element 3, 
-#   k_theta, theta_0, cutoff
-#
-# (ijj)-->determines cutoff for i-j distance
-# (jik)-->determines k, theta_0 for i-j-k angle term
-#
-# ielem jelem kelem	k     theta_0 cutoff
