December 20, 2019: Enable Structure Searching with Deuterium and Tritium

Explicit structure searching of deuterium (D) and tritium (T) atoms has been enabled.

Structures with explicit D or T atoms can be searched across all result types:

In CAS Draw, the D and T atoms are accessed via the bottom toolbar as shown in the screenshot below, and are selected and used in the editor the same as any other atom.

In ChemDoodle, the D and T atoms are accessed via the atom button on the floating toolbar as shown in the screenshot below.

Exceptions

A D or T atom cannot be attached to a generic group (Ak, Cy, Cb, Hy). If a structure is drawn that attaches a D or T atom to a generic group, an error message displays after the user clicks the OK button.   

Single-atom variables (X, M, A, Q) may be attached to D or T atoms.
