WebAbsorption Peaks. Carbon dioxide absorbs infrared radiation (IR) in three narrow bands of wavelengths, which are 2.7, 4.3 and 15 micrometers (µM). This means that most of the heat producing radiation escapes it.

According to quantum mechanics, atoms and molecules can only hold certain defined quantities of energy, or exist in specific states. When such quanta of electromagnetic radiation are emitted or absorbed by an atom or molecule, energy of the radiation changes the state of the atom or molecule from an initial state to … See more According to quantum mechanics, atoms and molecules can only hold certain defined quantities of energy, or exist in specific states. When electromagnetic radiation is absorbed by an atom or molecule, the … See more Electronic transitions Electromagnetic transitions in atoms, molecules and condensed matter mainly take place at energies corresponding to the UV and visible part of the spectrum. Core electrons in atoms, and a lot of other phenomena, are … See more In oxygen: • the Hopfield bands, very strong, between about 67 and 100 nanometres in the ultraviolet (named … See more When a photon is absorbed, the electromagnetic field of the photon disappears as it initiates a change in the state of the system that absorbs the photon. See more A wide variety of absorption band and line shapes exist, and the analysis of the band or line shape can be used to determine information about … See more Materials with broad absorption bands are being applied in pigments, dyes and optical filters.
