At octahedral sites in the close packed oxide lattice of Al 2 O 3 , the color of ruby being red due to the presence of Cr ( III ) is given. The crystal field splitting diagram of Cr ( III ) in the given environment, the variation of pressure in ruby crystal as a function of wavelength are to be determined. Concept introduction: A model that depicts the breakage of the degeneracies of the electron orbital states because of a static electric field is known as crystal field theory. The static field is produced by the surrounding charge distribution. Crystal field theory is based on the degeneracy of d -orbitals when they come in contact with the ligand. To determine: The crystal field diagram of Cr ( III ) and the variation of wavelength as a function of pressure.
