IR spectroscopy

In the past years, infrared spectroscopy has proven to be our workhorse for studying the chemistry of oil paint chemistry. While taking a simple IR spectrum is routine for many chemists, we have made some progress in pushing the possibilities of IR spectroscopy to maximise the information we can get about our samples.

Band deconvolution

With a heterogeneous material like oil paint, we are nearly always confronted with the problem of band overlap.  Obtaining quantitative data on the concentration or evolution of chemical species is only possible when you can accurately measure the intensity of each component band.
