| Abstract: | The interferogram of light transmission through Nd-2O-3 solution in HNO-3 was measured by Michelson interferometer with sub-femtosecond time resolution. Light emitting diode (LED) was applied as a light source and the absorption spectrum of Nd-2O-3 solution was obtained by Fourier transforming the recorded interferogram. The feasibility of using LED for Fourier transform spectroscopy was demonstrated. |
