WebFor most elements, there is a certain temperature at which their emission and absorption lines are strongest. The lines you see in a star's spectrum act like thermometers. Some compounds, like titanium oxide, only appear in the spectra of very cool stars. Others, like helium, appear only in the spectra of very hot stars. WebThe absorption spectrum is a plot of the absorbance of a sample as a function of wavelength. This plot can be used to help identify an unknown sample since some compounds have characteristic absorption spectra. Figure 6 shows the absorbance spectrum in the visible region for a complex metal ion. Maximum absorption for this ion …
