- Description
- Raw and normalized (baseline-corrected) MIR absorbance spectra of several matrix grains of QUE99177 (CR Chondrite) pressed on a diamond window and measured under vacuum at ambient temperature (22°C) and after heating at 300°C
- Number of spectra
- 27
- 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 temperatures 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.
