Convert a character string representing an elemental formula to a list representing the elemental formula. The list can be used as input to other functions.
character string representing the elemental formula.
To maintain compatibility with
the elemental formula can contain only C,H,N,O,S,P,Br,Cl,F,I,Si, and
Sn (I and Sn are default elements in
MolecularWeight only). Elements not in this set will be ignored and a warning will be
generated. The function can handle repeated elements, but not element
multiplication indicated by parenthesis.
Known issue: Lower case letters after numbers, such as the “o” in “C12oBr5H5” will not be caught with a warning and the resulting list will contain the incorrect number of elements.
