title: Unusual para-substituent effects on the intramolecular hydrogen-bond in hydrazone-based switches.
abstract: A "V"-shaped Hammett plot shows that resonance-assisted hydrogen bonding does not dictate the strength of the intramolecular hydrogen bond in the E isomers of hydrazone-based switches because it involves an aromatic pyridyl ring.
