We published a nice paper in the journalĀ Science Advances, where we used 2D-IR spectroscopy to elucidate the molecular structure of zinc carboxylates in oil paint films that contain the pigment zinc white. This research has solved the long-standing question about the origins of the broad carboxylate band in IR spectra of zinc white paint films. With this work, we are learning a lot about the inherent reactivity of zinc white paint layers, and the potential effects of water exposure/humidity on oil paint chemistry.
