The Absorption Coefficient of Solution for Monochromatic Radiation. 29 lying on the edge of the red-yellow absorption band, for this edge is extremely sharp compared to the edge of the analogous band of the water solution. The A — c curves for the region of transmission 764/z/z to 92(V//, and for the edge of the infra-red band 920juju to 1,134/4*, show that A for these regions of the spectrum remains approximately constant for all concentrations.
