密度函数D(r)= 2γ(r,r)− tSγ(r,r′)γ(r′,r)dr′,其中γ(r,r′)是一个无自旋的一级密度矩阵,已被提出作为描述分子中奇电子空间分布的基本公式.用D(r)方法研究了几种典型三原子物种的π电子成键性质。密度函数也可以成功地用于评估不稳定的单重基态分子的双自由基性质。
A density function D(r) = 2γ(r, r) − tSγ(r, r′)γ(r′, r) dr′, where γ(r, r′) is a spinless first-order density matrix, has been proposed as fundamental formula representing the spatial distribution of odd electrons in molecules. The bonding properties of π electrons in some representative triatomic species have been examined in the light of D(r). The density function can also be used successfully to assess the diradical character of unstable singlet ground-state molecules.
