Chemistry::Bond - Chemical bonds as objects in molecules
use Chemistry::Bond; # assuming we have molecule $mol with atoms $a1 and $a2 $bond = Chemistry::Bond->new( id => "b1", type => '=', atoms => [$a1, $a2] order => '2', ); $mol->add_bond($bond); # simpler way of doing the same: $mol->new_bond( id => "b1", type => '=', atoms => [$a1, $a2] order => '2', );
This module includes objects to describe chemical bonds. A bond is defined as a list of atoms (typically two), with some associated properties.
In addition to common attributes such as id, name, and type, bonds have the order attribute. The bond order is a number, typically the integer 1, 2, 3, or 4.
- Chemistry::Bond->new(name => value, ...)
Create a new Bond object with the specified attributes. Sensible defaults are used when possible.
Sets or gets the bond order.
Returns the length of the bond, i.e., the distance between the two atom objects in the bond. Returns zero if the bond does not have exactly two atoms.
Set or get whether the bond is considered to be aromatic.
Convert the bond to a string representation.
If called with no parameters, return a list of atoms in the bond. If called with a list (or a reference to an array) of atom objects, define the atoms in the bond and call $atom->add_bond for each atom in the list. Note: changing the atoms in a bond may have strange side effects; it is safer to treat bonds as immutable except with respect to properties such as name and type.
Calls $mol->delete_bond($bond) on the bond's parent molecule. Note that a bond should belong to only one molecule or strange things may happen.
