Absorption Images

1. Transmission images from Spec-files (BESSY, found wihtin one of the last columns)
2. Transmission (T) transformed into Absorption (A):
   A = 1-T
   –> T was determined with Fiji, looking for the highest intensity value within histogram and this is defined then as “100% transmission = 1 in formula”:
   a) 100% = 593751.44
   As -A = T - 1 and T = our image:
   with Fiji:
   → click on transmission image → process → math → substract 593751.44 → afterwards multiply with (-1)

RAMAN paper figure

## Compare with ORIGIN: peak width of peak with the highest intensity (number 1086). The peak width broadens the more the crystals (aragonite/calcite) lose the cristalinity and apear amorphous. I want to see if ACC is preesnt ##
