Water in fluorite crystal edges
Infrared measurements of water absorption (1450nm, 1950nm and >2500nm) in the brownish edges and through the blue central regions of a sample of fluorite exhibiting disulphide fluorescence (see previous post). This suggests that the water resides principally in the discoloured regions near the edges of the crystals.
The actual pathlengths through the crystals were 33mm (brown) and 24mm (blue).
