returns the geometry of a molecule
string; name or symbol of a molecule or structure
MolecularGeometry(molecule) returns the geometry of a molecule.
The molecule can be a name or CID number.
MolecularGeometry returns the molecular geometry as a Maple list of lists in the standard molecular geometry format of the QuantumChemistry package.
The standard geometry format of the QuantumChemistry package is a Maple list of lists which each list has 4 elements, the string of an atom's symbol and atom's x, y, and z coordinates.
Geometries and structures are retrieved from a web database. A connection to the internet is required. Currently, the procedure has access to over 96 million molecules contained in the PubChem database.
