Description:

Isotopic abundance of this atom's isotope.

This is an enumerated property. Acceptible values are shown in the following list:
Value CDXML Name Description
0 Unspecified Nothing is specified about the node's isotopic abundance
1 Any Node may match any node of the same element type, regardless of isotopy
2 Natural Node's element exists explicitly in natural abundance. Not valid when the node also has a specific isotopy
3 Enriched Node is enriched in the specified isotope. Not valid unless the node also has a specific isotopy
4 Deficient Node is deficient in the specified isotope. Not valid unless the node also has a specific isotopy
5 Nonnatural Node has a non-natural abundance of the specified isotope (may be either enriched or deficient). Not valid when the node also has a specific isotopy

If this property is absent:

The node is treated as having Unspecified isotopic abundance..
