WebDifferent molecules will absorb different wavelengths of light. The wavelengths of light for UV-visible absorption are from about 200 nanometers to 800 nanometers. This is a section of the electromagnetic spectrum pictured. Absorption of light starts with energy of a certain wavelength in this UV-visible region being exposed to a molecule. WebMost pigments work by absorbing certain wavelengths of light. Other wavelengths are reflected or scattered, which cause you to see those colours. At the atomic level, certain wavelengths of light are of the correct energy to excite specific transitions of electrons in the molecules or the solid.

WebJun 13, 2016 · If a molecule is polar (e.g., CO), then it can absorb IR light and be excited vibrationally, as this will necessarily change the dipole. However, a non-polar molecule … WebSep 9, 2024 · Light passing through a sample solution will partially be absorbed by molecules present in the sample. The amount of light unable to pass through a sample is measured as the absorbance value. Absorbance is directly proportional to the concentration of the molecules and is measured on a logarithmic scale from 0 to infinity.
