WebThe emission spectra in the visible field were recorded using excitation wavelengths of 450 and 550 nm. The transition states and their spectra are depicted in Figure 9 . Similar transitions can be detected in emission spectra with an excitation wavelength of 450 nm, whereas spectra with an excitation wavelength of 550 nm show a significant ...

Lithium by flame emis print - Department of Chemistry
WebThe spectra derived from low-energy sources such as flames are simpler than those from electrical discharges, although the temperature of flames and furnaces (2000–4000 K) is inadequate to excite many of the elements. Nevertheless, flame emission spectrometry is widely used for the determination of the alkali elements (lithium, sodium, and ... Weba relatively large quantity of lithium in a steel tube sufficient vapour was obtained to give an absorption spectrum showing 27 lines of the principal series. The method was the same as that described in the paper referred to, with the exception that a second steel tube was placed in the outer steel absorption tube. spaceflakes
