crystal field theory

Target entity: crystal field theory
Context triple: [Laporte rule, usedIn, crystal field theory]

• A. Jahn–Teller effect
  The Jahn–Teller effect is a phenomenon in molecular and solid-state physics where electronically degenerate states cause spontaneous geometric distortions that lower a system’s symmetry and energy.
• B. Goodenough–Kanamori rules
  The Goodenough–Kanamori rules are a set of semi-empirical guidelines that predict the sign and strength of superexchange magnetic interactions between ions in transition-metal oxides based on bond angles and orbital overlap.
• C. Advanced Inorganic Chemistry (with F. Albert Cotton)
  Advanced Inorganic Chemistry (with F. Albert Cotton) is a seminal graduate-level textbook that systematically presents the principles, structures, bonding, and reactivity of inorganic compounds and has long been a standard reference in the field.
• D. Van Vleck paramagnetism
  Van Vleck paramagnetism is a quantum-mechanical form of paramagnetism arising from the mixing of electronic energy levels by an applied magnetic field, even in systems with no permanent magnetic moment in the ground state.
• E. density functional theory
  Density functional theory is a quantum mechanical method for calculating the electronic structure and properties of many-body systems, widely used in physics, chemistry, and materials science.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.

Target entity: crystal field theory
Target entity description: Crystal field theory is a model in inorganic chemistry that explains the electronic structure, colors, and magnetic properties of transition metal complexes by describing how metal d orbitals interact with surrounding ligands treated as point charges.
