# 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
