Absorptionsmönster

Absorptionsmönster refers to the characteristic way a substance absorbs electromagnetic radiation at different wavelengths. When electromagnetic radiation interacts with a substance, some of the energy is absorbed, while the rest is transmitted, reflected, or scattered. The specific wavelengths that are absorbed depend on the electronic structure and molecular vibrations of the substance.

These patterns are often visualized as absorption spectra, which are plots of absorbance versus wavelength. Different substances have unique absorption spectra, making them useful for identification and quantification. For instance, in chemistry, absorption spectra are used to identify unknown compounds or to determine the concentration of a known substance in a solution. In physics, they can reveal information about the energy levels of atoms and molecules.

In biology, absorption patterns are crucial for understanding processes like photosynthesis, where chlorophyll absorbs light in specific regions of the visible spectrum. Medical applications include using absorption spectra for diagnostic purposes, such as in pulse oximetry, which measures blood oxygen saturation by analyzing how light is absorbed by hemoglobin. Analyzing these patterns helps scientists and engineers understand the fundamental properties of matter and its interactions with light.
