Description
Raw, normalized and baseline-corrected Mid-IR spectra of several matrix grains of EET92042 (pressed on diamond) under vacuum at ambient temperature and 300°C
Number of spectra
19
Variable type(s)
  • spectrum type
  • chemical variability
  • temperature
Instrument
Brucker Vertex 70 + Hyperion 3000 – micro-transmission Mid-IR
Sample holder
The diamond windows were loaded into a cell, enabling temperature up to 300°C under vacuum (from 10-4 mbar down to 10-7 mbar). Optical access is permitted from both sides of the cell through KBr windows, thus enabling measurements in transmission.
