24. The calibration measurements at room pressure were performed only on the front diamond of the cell. Notice that a calibration measurement on the whole cell does not provide useful information, being affected by unwanted contributions from the back diamond of the cell and pressure transmitting medium, that are not present in PPV reflectance spectra. Indeed, the PPV film adheres to the front diamond surface. This configurations was necessary to perform reflectance measurements, which require a flat sample surface, perpendicular to the incident beam.
