Abstract
Absorption spectra of selected microsections of materials with pressure-sensitive absorption bands mounted in diamond-anvil high-pressure cells were determined. The shift in the absorption peak, combined with data obtained at uniform pressure, permits calculation of the pressure of the microsection selected. Examples of a parabolic decrease in pressure from the center to the edge of the diamond anvil are demonstrated by contour diagrams.Keywords
