Valence

Overview

Turning on valence will enable the display of double bonds.
Toggling valence_mode alters the positioning of double bonds (for representation as Lines)
Note that bonds can be edited to be delocalized using Unond and Bond.

Examples

• 

  set valence, 0
  #(no double bonds)

• 

  set valence, 1
  set valence_mode, 1
  #bonds inside

• 

  set valence, 1
  set valence_mode, 0
  #bonds centered

• 

  set valence, 1
  #delocalized bonds
  #(edited: see Bond)

Syntax

set valence, 0 # off
set valence, 1 # on

set valence_mode, 0 # centered
set valence_mode, 1 # inside

# In editing mode:
# select the bond using Ctrl-right-click, then enter:
unbond pk1,pk2
bond pk1,pk2,4
# 1: single bond, 2: double bond, 3:triple bond, 4:delocalized
