Indirect optical analysis of a dynamic chemical system. | LitMetric

Indirect optical analysis of a dynamic chemical system.

Angew Chem Int Ed Engl

Department of Chemical Sciences, University of Padova and CNR ITM, Padova Section, Via Marzolo 1, 35131 Padova, Italy.

Published: July 2009

Reaction of the reference compound with a scavenger generates a characteristic UV/Vis signal that is independent of the molecular structure of the target.
