The BondDistances(molecule) calling sequence returns all of the bond distances in the molecule as a table.  

The $\mathbf{BondDistances}\left(\mathbf{molecule}\mathbf{\,}\mathbf{ }\mathbf{i}\mathbf{\,}\mathbf{ }\mathbf{j}\right)$ calling sequence returns the bond distance between the i and j atoms in the molecule.

The $\mathbf{BondDistances}\left(\mathbf{molecule}\mathbf{\,}\mathbf{ }\left[\mathbf{i}\mathbf{\,}\mathbf{j}\right]\right)$ calling sequence returns the bond distance between the i and j atoms in the molecule.

The $\mathbf{BondDistances}\left(\mathbf{molecule}\mathbf{\,}\mathbf{ }\left\{\mathbf{i}\mathbf{\,}\mathbf{j}\right\}\right)$ calling sequence returns the bond distance between the i and j atoms in the molecule.

The BondDistances(molecule[i], molecule[j]) calling sequence returns the bond distance between the i and j atoms.

The bond angles are returned as floats in units of the given data.
