Fourier Transform IR (FTIR)

Fourier Transform IR (FTIR). Most modern IR absorption instruments use Fourier transform techniques with a Michelson interferometer . To obtain an IR absorption spectrum, one mirror of the interferometer moves to generate interference in the radiation reaching the detector.

The Braggs and X ray Crystallography

The Braggs and X ray Crystallography. By sending radiation through crystal structures you should be able to produce diffraction around the atoms. To find the structure of materials they wanted to use very small wavelengths of radiation. Why are electrons go for studying matter?
