 NAME
BOND – Read stretching potential parameters

 SYNOPSIS
BOND
...
typ1  typ2   $K_{stretch}$ $r_0$
...
END

 DESCRIPTION
The command reads a sequence of stretching potential parameters. typ1 and typ2 are two character strings, not to exceed 7 characters, indicating the atom types of the two atoms involved in the stretching interaction. $K_{stretch}$ and $r_0$ are the stretching force constant and the stretching equilibrium distance, respectively. The units used for the $K_{stretch}$ and $r_0$ are Kcal mol$^{-1}$ Å$^{-2}$ and Å.
