本文解析了同位素标记的~(63)Cu-~(14)N-HAP,~(65)Cu-~(14)N-HAP,~(63)Cu-~(15)N-HAP。~(65)Cu-~(15)N-HAP,和Cu-~(15)N-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~(63)Cu和~(63)Cu的超精细分裂,而且还得出分辨较好的~(14)N和~(15)N的超超精细分裂。比较合理地确定了g_x,g_y,g_z;A_x~(65),A_y~(65),A_z~(65)和A_x~(63),A_y~(63),A_z~(63)以及A_∥~(15),A_⊥~(15)和A_∥~(14),A_⊥~(14)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。
The isotope labeled ~ (63) Cu- ~ (14) N-HAP, ~ (65) Cu- ~ (14) N-HAP and ~ (63) Cu- ~ (15) N-HAP were analyzed. ~ (65) Cu- ~ (15) N-HAP, and Cu- ~ (15) N-HAP were measured in tetrahydrofuran at 77K. The ultrafine splitting of ~ (63) Cu and ~ (63) Cu was not only obtained from the plot, but also the superfine splitting of ~ (14) N and ~ (15) N with better resolution was obtained. A_x ~ (65), A_y ~ (65), A_z ~ (65) and A_x ~ (63), A_y ~ 63, A_z ~ 63 and A_ ~ (15), A_⊥ ~ (15) and A_∥ ~ (14), A_⊥ ~ (14). The key parameters were calculated using the measured spectral parameters, and the electronic structure and bonding properties of the complexes were discussed. Satisfactory results were obtained.
