This article summarizes basic aspects of time-dependent density functional theory (TD-DFT) and its applications in inorganic chemistry. Sections titled TD-DFT and Spectroscopic Properties outline some of the theoretical formalism and explain how excitation energies can be obtained from TD-DFT linear response theory. Common approximations in density functional theory (DFT) exchange-correlation (XC) potentials that might have adverse effects on the accuracy of computed results are explained. Sections titled Benchmark Data and Some Case Studies discuss a number of case studies, with emphasis on TD-DFT excitation spectra computations in coordination chemistry. Computations of spectra and other properties of metals clusters are also discussed. Apart from excitation spectra, this section also describes TD-DFT computations of Raman intensities (including resonance Raman and surface-enhanced Raman spectra (SERS)), magnetic circular dichroism, optical rotatory dispersion (CD and ORD), and concludes with some comments on relativistic effects.
