Carbon monophosphide

Summary

Carbon monophosphide is a diatomic chemical with formula CP. It is a heavier analog of the cyanide radical (CN). CP and CN are both open-shell species with doublet Π ground electronic states while the ground states of CS and CO are closed-shell. The related anion, CP, is called cyaphide and isoelectronic with CS.
