is an option for Molecule and related functions that specifies whether hydrogen atoms should be explicitly included in the results.
- The following settings can be given:
|True||include or add in all necessary hydrogens explicitly |
|False||do not include or add in any hydrogens explicitly|
|Automatic||include only hydrogens that are explicitly listed|
- With the default setting of Automatic, hydrogens not listed in the molecule expression are treated as implicit.
- Physical properties such as molecular mass and formula will account for implicit hydrogens.
Basic Examples (2)
Create a molecule from an entity:
Create the same molecule with implicit hydrogen atoms:
Create a molecule only listing heavy atoms:
The hydrogens are not present in the expression, but influence properties such as mass and formula:
Three implicit hydrogens are bonded to the carbon atom, and one to the oxygen. These do not count toward structural operations such as AtomCount and AtomList:
Properties such as molecular mass and formula that reference the physical molecule will account for the hydrogens:
