Independence complex

It is convenient, for simple systems, to have explicit expressions for equation (B2.4.17). Since the original matrix is non-Hemiitian, the matrix fomied by the eigenvectors will not be unitary, and will have four independent complex elements. Let them be a, b, c and d, so that U is given by equation (B2.4.20). [Pg.2097]

Monochromatic Waves (1.14) A monochromatic e.m. wave Vcj r,t) can be decomposed into the product of a time-independent, complex-valued term Ucj r) and a purely time-dependent complex factor expjojt with unity magnitude. The time-independent term is a solution of the Helmholtz equation. Sets of base functions which are solutions of the Helmholtz equation are plane waves (constant wave vector k and spherical waves whose amplitude varies with the inverse of the distance of their centers. [Pg.278]

A few thioether-ligated copper(II) complexes have been reported, however (cf. Section 6.6.3.1.2) (417) (essentially square planar), (418) (two crystalline forms one TBP and other SP),361 (419) (SP),362 (420) (SP),362 (421) (TBP),362 (422) (SP),363 (423) (SP),363 (424) (two independent complexes SP and octahedral),364 (425) (TBP).364 In the complexes (420) and (421), EPR spectra revealed that the interaction between the unpaired electron and the nuclear spin of the halogen atom is dependent on the character of the ligand present. For (424) and (425), spectral and redox properties were also investigated. Rorabacher et al.365 nicely demonstrated the influence of coordination geometry upon CV/Cu1 redox potentials, and reported structures of complexes (426) and (427). Both the Cu1 (Section 6.6.4.5.1) and Cu11 complexes have virtual C3v symmetry. [Pg.826]

In a U(l) invariant theory, the pure gauge vacuum is defined by a scalar internal gauge space in which there exist the independent complex scalar fields ... [Pg.157]

Contrary to the point by point approach the diagonalization method consists of the generation of an entire lineshape function in one step. (13, 14, 57-60) Time-consuming calculations are carried out only once. The resulting set of complex numbers can be used for a simple calculation of the lineshape (absorption and dispersion modes) at any desired point on the frequency axis. Thus, the complex matrix from equation (147) can be diagonalized by a similarity transformation using an co-independent complex matrix W ... [Pg.262]

It is easy to check that the rows and columns of this matrix are orthogonal and its determinant equals unity. The independent complex matrix elements in eq. (3.45) are known as Cayley-Klein parameters of the rotation group. Also, one can see that for quaternions connected by the relation r = ri o r2 the corresponding 2x2 matrices are connected by the same relation with replacement of the quaternion multiplication by the usual matrix product. This establishes isomorphism between the SU(2) group and the group of normalized quaternions HP which can be continued to the homomorphism on 50(3). [Pg.223]

Recently, the group of Arpalahti [39] studied the cd-[(NH3)2Pt(Ado-N(7))i]2+ (Ado = adenosine) system. There are two independent complex cations in the unit cell, both exhibiting a head-to-tail orientation. The Pt-N(7) distances are within the range 2.00-2.05 A, and the dihedral angles between the bases are 83.5° and 86.6°. [Pg.327]

Very few structural studies have been concentrated on models of ApG adducts of cisplatin. Conformational analysis of two rotameric forms of the complex m-[Pt(NH3)2(9-MeA-A(7))(9-EtGH-A(7))]2+ has recently been described [40], One of the forms, crystallized as a PI 6 salt, can be characterized as a right-handed helicoidal model for the intrastrand ApG crosslink in double-stranded DNA. The bases in this compound assume a head-to-head orientation (Fig. 6) with the interbase dihedral angles of 81.8° and 87.5°. There are two independent complex cations in the unit cell. The left-... [Pg.327]

In competitive inhibition, both inhibitor and substrate can bind to enzyme and form two independent complexes. Only ES degrades to products El is considered a dead-end. Because the inhibitor binds, to the active site, the substrate carmot (and vice versa), so there carmot be an ternary ESI complex (Fig. 6.6). [Pg.194]

Similarly, non-interfering, independent complexing agents with a pH adjustment can be used to complex the two cations as shown in the following case [58b]. [Pg.289]

Kim (2004) illustrated the four causalities of complexity with respect to the design axioms (Fig. 2). Type 1 complexity is a result of heavy coupling of the functional requirements, which is a violation of the independence axiom. Time-independent complexity is a type II complexity and is a result of the information axiom violation. [Pg.233]

There are two kinds of time-independent complexity real and imaginary. Time-independent real complexity is defined as a measure of uncertainty when the probability of achieving the FR is less than 1.0 because the system range does not lie inside the design range. The real complexity... [Pg.234]

Our first real application is concerned with the independence complexes of graphs, which were defined in Subsection 9.1.1. Recall that for an arbitrary integer n > 1, we let denote the graph consisting of n vertices and n — 1 edges that connect these vertices so as to form a string. [Pg.193]

For an arbitrary integer n > 2, we let C denote the cycle with n vertices. These vertices are labeled 1,.. .,n, with arithmetic operations on labels performed modulo n. The homotopy type of the independence complexes of cycles allows an easy description as well. [Pg.194]

We have defined the independence complexes of graphs in Subsection 9.1.1, Definition 9.2. Sometimes, it can be convenient to view the simplicial complex Hom+(G, R) as the independence complex of a certain graph. [Pg.351]

Corollary 20.6. For an arbitrary graph T, the simplicial complex Hom+(T,iC ) is isomorphic to the n-fold join of the independence complex ofT, which in our notation is called Ind(T) ". [Pg.352]

The question may be answered in the structural change in complex of 2, which has two pyridine complexes and solvate methanol molecules in its asymmetric unit of the P2i cell [35, 36]. The crystal structure viewed along the c axis before photoirradiation at 223 K is shown in Fig. 3.24. Two crystallographically independent complexes, A and B, without axial ligands and surrounding methanol molecules are shown in Fig. 3.25a. The 1-mce group of A has syn, while that of B has anti conformation. [Pg.46]
