自旋交叉复合物的密度泛函理论计算

Density Functional Theory Calculations for Spin Crossover Complexes

Hauke Paulsen, Alfred Xaver Trautwein

摘要:

密度泛函理论(DFT)为分子和晶体的电子结构的有效和相当精确的计算提供了理论框架。密度泛函理论的主要特点进行了描述和DFT方法进行了比较,基于波函数的方法,如Hartree-Fock方法。本文综述了密度泛函理论在自旋交叉络合物中的应用,穆斯堡尔参数的计算,振动模式和高自旋和低自旋异构体之间的熵,振动能和总电子能量的差异。

英文摘要:

Density functional theory (DFT) provides a theoretical framework for efficient and fairly accurate calculations of the electronic structure of molecules and crystals. The main features of density functional theory are described and DFT methods are compared with wavefunction-based methods like the Hartree-Fock approach. Some recent applications of DFT to spin crossover complexes are reviewed, e.g., the calculation of Mössbauer parameters, of vibrational modes and of differences of entropy, vibrational energy, and total electronic energy between high-spin and low-spin isomers.
