How many organic compounds are graph-theoretically nonplanar?

Research output: Journal contributionsJournal articlesResearchpeer-review

Authors

Most graphs and most 4-graphs are nonplanar, whereas most compounds of
Organic Chemistry are gt-planar. This potentially useful fundamental difference between
graphs and compounds was empirically obtained by testing for gt-planarity representative
graphs and all compounds in the Beilstein file. The Beilstein search did uncover compounds
whose gt-nonplanarity was hitherto unknown. gt-Nonplanar peptides/proteins were retrieved
from the CAS Registry file.
