11. Electronic transition bands of molecules may be from tens to several hundred nanometers in breadth.12. Electronic transitions occur in the vacuum ultraviolet regions.13. Franck Condon considerations can also be applied to the electronic transitions of chromophores dissolved in liquids. 14. :: What about the case of electronic transitions ? 15. In Doppler cooling, the frequency of light is tuned slightly below an electronic transition in the atom. 16. Optical properties of carbon nanotubes derive from electronic transitions within one-dimensional density of states ( DOS ). 17. The formation of the dative state is an electronic transition giving rise to the colorful absorption bands. 18. Figure 1 shows the typical line shape for electronic transitions of individual chromophores in a solid matrix. 19. The electronic transition responsible for this absorption is a transition from the 5d to the 6s level. 20. Each electronic transition may show vibrational coarse structure, and for molecules in the gas phase, rotational fine structure.
