In this paper, by using point mass model, the normal coordinate lanalysis calculations of La(15-C-5) (NO_3~-)_3 and La (18-C-6) (NO_3~-)_3 are performed to give theoretical results in agreement with frequencies and intensities of infrared and Raman bands. In the calculations, the same force constants with respect to the two molecules are adopted and some internal coordinates which are less important are neglected. Furthermore, the properties of coordination bonds, approximation calculation method and other related problems are discussed. 相似文献

In this paper, the authors proved that finding all solutions of a given multivariate polynomial system is equivalent to solving a relative joint eigenvalue problem(Theorem 1) and in some cases one can find all solutions of the given system from the eigenvalues and vectors of one matrix or matrix pencil (Theorem 2). Especially the situation that the ideal generated by the given system is 0-dimensional is discussed. 相似文献

稀土环己烷酸配合物合成及振动光谱研究 总被引:2,自引:0,他引:2
The solid state complexes of trivalent lanthanid, yttrium and scandium with cyclohexane carboxylic acid have been isolated and characterized by IR and Raman spectroscopy. It was found that there are only chelated carboxylate groups in the scandium complex and that there are the chelated, bridged and chelate-bridged carboxylate groups in other rare earth complexes. The former is a mononuclear complex and the latter is a polynuclear polymer. The RE—O coordinate bonds possess the characters of convalent ionic bond. 相似文献
