Thus, for the mass numbers 93 and 141, the following isobaric fission-product decay chains would be formed (the half-lives for the beta-decay processes are indicated above the arrows): (The left subscript on the element symbol denotes Z, while the superscript denotes A).
The first element is the element symbol of the atom.
The name of the abbreviation is defined in lieu of the element symbol, and the structural fragment is defined completely within the extension field.
In the current version, jCompoundMapper features the following typing schemes as labeling function l ( a i ) → a ^ i : 1. Element symbol (e.g. C, O, N,...) 2.
The new code defines the atom types using a list that specifies for each type the element symbol, hybridization, formal charge, number of lone pairs, and an enumeration of the bond orders (see Fig. 1).
If the abbreviation atom is created in the same way as for an ordinary element symbol, saving the structure as an MDL Molfile would be equivalent to the text shown in (c).
