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 … WebAbstract. The mechanisms of magnetoreception have been proposed as the magnetite-based, the chemical radical-pair and biocompass model, in which magnetite particles, …
