They exist predominately as zwitterionic resonance structures where the nitrogen and carbon atoms are double bonded to each other so that both nitrogen atoms are essentially planar (in sp2 orbital hybridization). Recently, functional mri (fmri) entered the field of neuropharmacology to explore the intracerebral sites and mechanisms of action of pharmacological agents. Caffeine has 49.48% composition carbon, 5.19% composition hydrogen, 16.48% composition oxygen, and 28.85% composition nitrogen.
