摘要
目前ENDOR技术已成功地用于解析被包络在EPR峰宽中的配体的超精细耦合或核的电四极耦合信息。当ENDOR技术用于单晶样品时,它可以提供详细而丰富的结构信息,但是当ENDOR技术用于粉末或溶液样品时,即使用定向选择测定等改进的方法,所能得到的信息还是很有限。然而在很多场合,因为单晶样品不可能得到,所以必须对粉末或溶液样品进行测定.本工作就是试图从粉末或冷冻溶液样晶中得到更多的结构信息.
The work in this paper is one of the attempts to obtain more structural information from powder or frozen solution samples. The copper (Ⅱ) complexes with nitrogen as donor atoms in the form of N4 , cis N2O2 , trans -N2O2 and NO, donor sets on the equatorial plane is treated. In this paper we will show that the magnitudes of the nitrogen hypcrfine couplings have some correlation with the donor sets as well as types of nitrogens, and the found correlation is useful for estimation or confirmation of coordination structure of copper ( Ⅱ) complexes with unknown or uncertain structure.
