Infrared analysis was performed at the offline experimental station of SISSI-Bio beamline of Elettra Sincrotrone Trieste.33 Samples were measured in powder form. Measurements were carried out through the help of a Vertex70v interferometer equipped with a single reflection monolithic Diamond ATR crystal (platinum, Bruker Optics) and a DTGS (Deuterated Triglycine Sulphate) detector, working at a speed of 7.5 kHz and a KBr beamsplitter. The interferometric setup was used in combination with a glow-bar source allowing access to the spectral region between 1000 and 4000 cm-1. For each spectrum, 256 scans were accumulated and averaged for each sample, Fourier transformed, then referenced with the spectrum of the clean ATR crystal. The Fourier Transform was performed by applying a 3-terms Blackman Harris apodization filter.
