Abstract
The excited-state intramolecular proton-transfer compound methyl 2-hydroxy-6-methylnicotinate (MHMN) has been investigated. The ortho position of the hydroxyl group with respect to the pyridine nitrogen for MHMN results in significantly different molecular properties than the molecule that has the hydroxyl group in the meta position. The ground-styate lactim-lactam equilibrium constant for MHMN is calculated to be 0.065±0.006 in n-hexane by the absorption measurement
