This causes an absorption spectra, as shown below. Because the energy levels are the same, the lines in the emission spectra of an element are in the same position as the lines in the absorption ...

Finally a bibliography of books and web sites is given for further and ... cubic environments then the transition energies are identical and this produces a spectrum as shown in Fig4: a single ...

WE have recently completed an examination of the infra-red absorption spectra of the monoxide and dioxide of chlorine. The unstable nature of these substances demanded the use of a monochromator ...
