FineChem Model Input

Bridged rings should be counted as +1 for every bridge. Linked rings count each ring. For example, naphthalene and camphor both count as 2 rings.

For example, Toluidine counts as 2. Trichlorobenzene counts as 1. Note that ring systems can also be substituents to other ring systems, e.g. 1-chlorobiphenyl computes to 3.

(i.e. aldehydes or ketones)
