| beer-lambert law | The equation A=ECL, where A is the absorbance at a given wavelength of light, E is the molar extinction coefficient, C is the concentration of the molar solution, and L is the length of the light path. In words, the equation means that the concentration of a substance in moles is proportional to the absorption of a given wavelength of light by a solution of the substance. The equation is used in the study of spectroscopy. (09 Oct 1997) |
| Beer's law | The intensity of a colour or of a light ray is inversely proportional to the depth of liquid through which it is transmitted; it is concluded that the absorption is dependent upon the number of molecules in the path of the ray. Compare: Beer-Lambert law. (05 Mar 2000) |
