【摘要】 利用二维红外相关光谱对一种新颖的多聚硼钒酸盐{(VO)10[V14O28(OH)4]2}{Zn4(B2O4)(BO3)2} [Zn(NH2CH2CH2NH2)2]6 1进行了研究,清晰地观察到簇阴离子在磁微扰下结构的细微变化,簇骼骨架振动和簇单元中的O-V-O的伸缩振动对于磁场的变化比较敏感,而V=Ot的伸缩振动对磁场变化不敏感。更多还原

【Abstract】 A novel polyoxovanadium borate, {(VO)10[BnO28 (OH)4]2} {Zn, (B2O4) (BO3 )2 }[Zn(NH2CH2CH2NH2 )2]6, was studied by 2D correlation IR spectroscopy, and the subtle structural changes of POMs during the magnetism variation were clearly probed by the 2D correlation IR spectroscopy. The 2D IR correlation spectroscopy shows strong auto peaks near 550, and 700-800 cm-1, indicating that the intensity changes of O-V-O stretching vibration are sensitive to the magnetism variation .更多还原
