摘要: 本文解析了同位素标记的63Cu-14N-HAP,65Cu-14N-HAP,63Cu-15N-HAP。65Cu-15N-HAP,和Cu-15N-HAP,等五种配合物在四氢呋喃中,在77K温度下测得的分辨较好的ESR波谱。从图上不仅得到了63Cu和63Cu的超精细分裂,而且还得出分辨较好的14N和15N的超超精细分裂。比较合理地确定了gx,gy,gz;Ax65,Ay65,Az65和Ax63,Ay63,Az63以及A15,A15和A14,A14等张量参数。利用测得的波谱参数计算了键参数,并讨论了配合物的电子结构及成键特性,得到了较满意的结果。

Abstract: A better resolution of ESR spectra of labelled 63Cu-14N-HAP,65Cu-14N-HAP, 63Cu-15N-HAP, 65Cu-15N-HAP and Cu-15N-HAP complexes in tetrahydrofuran (THF) solution, measured at 77K, was analyzed. From the spectra, we have got not only hyperfine splitting of the 63Cu and 65Cu; but also very nice superhyperfine splitting arising from 14N and 15N nuclei. The gx,gy,gz;Ax65,Ay65,Az65; A15,A15,A14,A14 etc. tensor parameters were determined rather reasonably. The bonding parameters were calculated by using measured spectral parameters, and its electronic structure and the bonding character of these complexes are discussed, and better satisfactory results were obtained.
