  • What is the crystal field theory?

    Crystal field theory (CFT) describes the breaking of orbital degeneracy in transition metal complexes due to the presence of ligands.
    CFT qualitatively describes the strength of the metal-ligand bonds.
    Based on the strength of the metal-ligand bonds, the energy of the system is altered.

  • What are the basic assumptions of crystal field theory?

    The central assumption of CFT is that metal–ligand interactions are purely electrostatic in nature.
    The color for a coordination complex can be predicted using the Crystal Field Theory (CFT).
    Knowing the color can have a number of useful applications, such as the creation of pigments for dyes in the textile industry.

  • What is t2g and eg?

    In a crystal field theory, the t2g and eg orbitals are the split d-orbitals of a transition metal ion.
    The t2g (triplet, lower energy) orbitals are the dxy, dxz and dyz orbitals.
    The eg (doublet, higher energy) orbitals are the dz^2 and dx^2-y^2 orbitals.

  • What is t2g and eg?

    10Dq is called crystal field splitting energy.
    Significance: 10 Dq - The energy separation between the two levels.
    The e-orbitals are repelled by an amount of 0 6 ?.
