Description
Normalized Mid-IR absorbance spectra (baseline corrected) of matrix and IOM fragments extracted from unshocked and shocked (at 5, 10, 20 and 40 GPa) Murchison (CM2 chondrite) acquired under vacuum and at T = 80°C
Number of spectra
15
Variable type(s)
  • sample composition
Instrument
Brucker Vertex 70 + Hyperion 3000 – micro-transmission Near-IR
Sample holder
The diamond windows were loaded into a cell, enabling temperature up to 300°C and controlled pressure (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.
