Investigated photodissociation of methylphenol molecules using advanced spectroscopic techniques, revealing that O-H bond fission occurs similarly to phenol and 4-fluorophenol.
Excitation to different energy states leads to H-atom loss through conical intersections, resulting in the formation of vibrationally excited methylphenoxyl radicals.
The position of the methyl group on the benzene ring significantly affects the energy disposal in the product and O-H bond strengths have been measured, showing destabilization effects particularly at the 3-position.

- David E Kelly's research primarily focuses on the photodissociation processes of substituted phenols, as evidenced by his detailed investigation of 4-, 3-, and 2-methylphenol.
- Utilizing advanced experimental techniques like resonance enhanced multiphoton ionization and Rydberg atom photofragment translational spectroscopy, he explores the mechanisms of O-H bond fission in these compounds.
- His findings reveal that the excitation of these phenols leads to H-atom loss through both direct and indirect pathways, highlighting the complexities of molecular behavior in photochemical reactions.
