FT-IR spectroscopy
All experiments were performed using a Nicolet iS10 FT-IR spectrometer
(ThermoFisher Scientific) using the Smart iTX™ ATR
attachment with the following settings: 64 scans, resolution 8, data
spacing 0.964 cm-1, range 4000-600
cm-1. Spectra were collected every 20 minutes over a
12-hour period. A background spectrum was collected prior to application
of the oil/drier mixture.
