用逆光电子能谱（IPES）和近边X射线吸收谱（NEXAFS）研究了无金属酞菁（H2PC）、镍酞菁（NiPC）和铜酞菁（CuPC）在单晶表面的分子轨道.在实验数据中观察到的功能分配参考分子轨道计算。吸附在Cu（110）表面的NiPC分子的碳和氮的1sNEXAFS测量表明，酞菁分子平面平行于表面。在Ni LIII和LII边缘记录的X射线吸收数据显示未占据的Ni 3d能级位于酞菁环的平面内。
The unoccupied molecular orbitals of metal‐free phthalocyanine (H2PC), nickel‐phthalocyanine (NiPC), and copper‐phthalocyanine (CuPC) adsorbed on single crystal surfaces have been studied by inverse photoemission spectroscopy (IPES) and near‐edge x‐ray absorption spectroscopy (NEXAFS). The features observed in the experimental data are assigned by reference to molecular orbital calculations. Carbon and nitrogen 1s NEXAFS measurements of NiPC adsorbed on Cu(110) surface indicates that the phthalocyanine molecular planes are parallel to the surface. X‐ray absorption data recorded at the Ni LIII and LII edges show that the unoccupied Ni 3d level is located in the plane of the phthalocyanine rings.
