WebNov 24, 2011 · 1. Introduction. Raman spectroscopy is used to identify a wide variety of minerals and, in some instances, to provide chemical and structural information (Griffith, 1969, Pérez and Martinez-Frias, 2006).Some of this information can be obtained using other analytical tools, including X-ray diffraction (XRD), infrared (IR) spectroscopy, or Fourier … Webas iron oxides. In the proper geometry, iron oxide clusters can behave like a compass needle and magnetic bacteria use such a compass needle mechanism to find up and down. An alternative possibility is to use short-lived, specialized photochemical reac-tions, for which thermal noise does not have time to effectively mask effects of magnetic fields.
