There are two ways of calculating the absorption coefficient. 1.

E = A / mc. Where E is the extinction coefficient; A is the absorbance; mc is the molar concentration; Extinction Coefficient Definition. Extinction coefficient is defined as the ratio of absorbance to molar concentration of a solution. Energy Range: Energy Range 0.001 - 2.00 keV Energy Range 2.00 - 433 keV Sub Range -keV ρ (g cm-3) (optional, only used for the linear attenuation coefficient µ):. No frames. Absorption coefficient k = A/d, where A is absorbance (A= log (Io/I)), Io is intensity of the light beam before the sample, I is intensity of the beam, passed through the sample. d is the thickness While the SI unit is the absorption cross-section σ, the extinction coefficient ε (epsilon) is more often used.

While the SI unit is the absorption cross-section σ, the extinction coefficient ε (epsilon) is more often used. Typical ε values for visible wavelength absorption maxima are of the order of 1000 - 100,0000. A related calc can be used to calculate concentration from known OD, path length and absorption coefficient. Global Parameters Air temperature: 20 °C Air pressure: 101325 Pa Model: Allard & Champoux (1992) Absorber Parameters α m = mean absorption coefficient. S = total surface in the room (m 2) The acoustic characteristics of a room can be calculated with the formulas above, or estimated for typical rooms.
