Nuclear resonant scattering is a hyperfine spectroscopic technique that works in the time domain. This in contrast to Mössbauer spectroscopy which works in the energy domain. The technique makes use of very short pulses of synchrotron radiation which simultaneously excite all hyperfine-split resonances of the sample. When the excited states relax, the coherently emitted waves interfere and form a beat pattern in the time domain. Through Fourier transformation the frequencies can be obtained from which subsequently hyperfine parameters such as the magnetic hyperfine field, the quadrupole splitting en the isomeric shift can be acquired.
