用振动光谱学研究了Cu(py)n(NO3)2 （n= 2,3和4）和M(py)3(NO3)2 （M = Co， Ni和Zn）的金属配体环境的性质。广泛使用同位素取代和相关技术来分配低频红外光谱（350-75 cm-1）。对于Cu(py)n(NO3)2体系，随着硝酸键共价的增加，铜-氧拉伸振动向高能量转移，而铜-氮拉伸振动向低能量转移。
Vibrational spectroscopy has been used to investigate the nature of the metal–ligand environment of Cu(py)n(NO3)2 where n= 2, 3, and 4 and M(py)3(NO3)2 where M = Co, Ni, and Zn. Extensive use of isotopic substitution and related techniques were made to assign the low frequency i.r. spectra (350–75 cm–1). It has been observed for the Cu(py)n(NO3)2 system, that as the covalency of the nitrate bonding increases, the copper–oxygen stretching vibration shifts to higher energy, while the copper–nitrogen stretching vibration moves to lower energy.
