Basic Examples  (1)

Test whether a molecule pattern is valid:

Wolfram Language code: MoleculePatternQ[MoleculePattern[{"C", "C"}, {Bond[{1, 2}, "Single"]}]]

Not all patterns are valid:

Wolfram Language code: MoleculePatternQ[MoleculePattern[{"C", "C"}, {Bond[{1, 2}, "Snigle"]}]]

Scope  (2)

MoleculePatternQ works with patterns defined by SMARTS strings:

Wolfram Language code: MoleculePatternQ[MoleculePattern["[C+2]"]]

MoleculePatternQ works with patterns defined by explicit atom and bond lists:

Wolfram Language code: MoleculePatternQ[MoleculePattern[{"C" | "N", Atom[_, "AtomicNumber" -> GreaterThan[6]], "C", "C"}, {Bond[{1, 2}, _], Bond[{2, 3}, _], Bond[{3, 4}, _], Bond[{4, 1}, _]}, {}]]
