Are there publicly available datasets of visible (and UV and IR, if possible) spectral reflectance data for the different types of iron rust?
Specifically, I am involved with a project that has an interest in the spectral/optical properties the different types of rust, particularly the 'red' and 'green' rust.
Preferably, a publicly available source of the data would be ideal, though if the data is included as part of a published paper, even behind a paywall - that would be okay as well (one of my contacts would be able to access that through his university library). (If it turns out to be more than 1 resource, that is fine also).
While researching, it has become clear that through usual research channels, there is no obvious data sets for iron rust optical properties. Much of the data available is about the electrochemical properties, and most of those are charts.
