In the 2A1 distorted trigonal bipyramid structure ,the single non equivalent Ga atom has the population of 4s 4p ,while the two equivalent Ga atoms have the population of 4s 4p .this compares with a Ga population of 4s 4p in the undistorted D3h structure ,hence the jahn-teller distortion causes depletion of the charge density on the 4s orbital of the non-equivalent Ga atom, and enhancement of charge density on the 4s orbital for the two equivalent atoms .an opposite trend is observed for the 4p orbitals of these Ga atoms .the P population for the two equivalent atoms is 3s 3p .the populations of the other 2B1 state with the edge-capped tetrahedral structure are similar with the exception that all three Ga atoms have similar but not identical populations .

在2A1被变形的三角bipyramid结构，唯一非等效Ga原子有4s 4p的人口，而二个等效Ga原子在未变形的D3h结构有4s 4p 。this的人口和4s相比4p的Ga人口，因此jahn出纳畸变在non-equivalent Ga原子的4s轨道导致电荷密度的取尽，并且电荷密度的改进在4s轨道为二个等效原子。an在趋向对面对这些Ga原子4p轨道被观察。the人口为二个等效原子是另一个2B1状态3s 3p 。the人口与边缘加盖的四面体结构是相似的P 除之外全部三个Ga原子有相似，但不相同人口。

In the 2a1 state of Ga3P2 ,the singly-occupied 5a1 orbital is made of Ga1....................on the other hand ,the 2b1 HOMO of the 2B1 state of the edge-capped tetrahedron consists of P1............................,where the P orbitals and Ga orbital make a significantly enhanced contribution .thus , while Ga orbitals make significant contributions to the 1A1 state with the distorted trigonal bipyramidal structure ,the P orbitals contribute significantly to the open shell MOs of the two structures.

另一方面在Ga3P2 2a1状态，被唯一占领的5a1轨道由Ga1做成。。。。。。。。。。。。。。。。。。。。，边缘加盖的四面体的2B1状态的2b1拉人包括P1 。。。。。。。。。。。。。。。。。。。。。。。。。。。。， P轨道和Ga轨道做显著改进的贡献。thus，而Ga轨道做对1A1状态的重大摊缴与被变形的三角bipyramidal结构的地方， P轨道对二个结构的开放壳MOs极大贡献。
