2.6: Lines Spectra- Emission and Absorption Lines
WebThe regions of low absorption are called atmospheric windows, because high energy solar UV can penetrate to lower altitudes than would be expected from averaged cross sections at these wavelengths. Figure 8.1 indicates the locations and strengths of many of these strong bands and deep windows. WebAccording 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 a final state.An absorption band … WebNov 25, 2024 · The absorption feature at 0.48 µm is due to electronic transition in carotenoid pigments, which work as accessory pigments to the chlorophyll in the photosynthetic process, and the 0.68 µm absorption is due to electronic transition in the chlorophyll molecule centred around the magnesium component of the photoactive site. buckley wanderers fc
