Is it true that for every bulk metal absorption and emission occur at approximately the same wavelength?
If the emission and absorption involve between the same quantum energy levels then then they should have the same wave length with an uncertainty, which is known as the natural line width. Lambda = h DEL(E) / c.
I look for the excel files to calculate nonlinear parameters of isotherm.
