列举配合物IR光谱伸缩振动频率v_(CN)～v(CS)、v_(MN)～v_(MS)的差异以判断键合异构的配位原子。为从E_m~*与E_n~*能级差的大小说明键合异构,对SCN~-进行了HMO处理。另外,还从反馈π键(M→L)、诱导效应和极化作用、空间效应等方面讨论了影响SON~-键合异构的结构因素。
The differences of v_ (CN) ~ v (CS) and v_ (MN) ~ v_ (MS) in IR spectral stretching vibration spectra of the complexes were investigated to determine the bonding heteroatom coordination atoms. In order to describe the bonding heterogeneity from the magnitude difference of E_m ~ * and E_n ~ *, HMO processing was performed on SCN ~ -. In addition, the structural factors that affect the SON ~ - bonding is discussed in terms of feedback π bond (M → L), inducing effect and polarization, and spatial effect.
