Fourier Transform Infrared Spectroscopy (FTIR) spectra were recorded with a
6200 spectrophotometer (JASCO, Pfungstadt, Germany) in the range 4000–600 cm
−1 with a 0.5 cm
−1 resolution and a well-plate sampler along with the Spectra Manager II software.
Raman spectra were recorded using a JASCO NRS-5100 Micro-Raman dispersive spectrophotometer in the range 3500–800 cm
−1 with a 6.48 cm
−1 resolution, with laser light source VIS-NIR with red diode at 785 nm with 500 mW of power (Torsana Starbright) refrigerated by air and the KnowItAII JASCO for Raman software.
