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
