Gravitational redshift was measured by Pound, Rebka, and Snider in Harvard's Jefferson Tower using this technique to detect a frequency shift of order one part in ten to the 14th. It can be used for precise studies of the Zeeman effect in nuclei. Iron 57 and tin 119 are two of the isotopes used in this type of spectroscopy due to narrow linewidths in their transitions. Before this technique, the large size of Doppler shifts relative to transition widths made nuclear spectroscopy problematic. It was discovered by its namesake when he was a graduate student at the Munich University of Technology. FTP, what is this effect in which a crystal lattice reduces recoil energy

When formed underneath glaciers, these landforms can cause devastating floods known as jokulhaups (yoe-kull-howps). A pyroclastic flow may stem from these landforms, which can excrete material known as pahoehoe (pa-HOY-hoy) and aa (ah-ah).
