 \idx*{bond!types}As we have already seen (see page~\pageref{types.liaisons}), bonds can be one of nine types, each corresponding to the characters \boxedfalseverb-, \boxedfalseverb=, \boxedfalseverb~, \boxedfalseverb>, \boxedfalseverb<, \boxedfalseverb{>:}, \boxedfalseverb{<:}, \boxedfalseverb{>|} and \boxedfalseverb{<|}.
