Axis types

Diffuorobenzene is a prolate asymmetric rotor and, because the y axis is the b inertial axis, type B rotational selection mles apply. In Figure 7.44(b) is a computer simulation of the... 

Whether of nM 7tL or n- -OL (off-axis) type, pi-backbonding interactions correspond to partial inclusion of ionic resonance structures featuring a metal-ligand double bond, as illustrated schematically in (4.79) for phosphine ligands ...

Hereafter, we will assume uniaxial anisotropy, of easy-axis type, given by Eq. (3.4) (if not otherwise indicated), since it is the simplest symmetry that contains the basic elements (potential minima, barriers) responsible for the important role of magnetic anisotropy in superparamagnets. Experimental evidence for uniaxial anisotropy is given in Refs. 15 and 16.

Point-dipolar interactions favor a perpendicular arrangement of the spins with respect to the ring plane and thus provide a hard-axis type contribution (D >0). " However, with few excep-the observed anisotropy largely exceeds the calculated dipolar term. For instance, in... 

An important aspect of one-dimensional magnetism is the nature of the magnetic interaction between the spins. It can be isotropic, as described by the spin Hamiltonian Equation (6), or anisotropic. In the axial limit the anisotropy can be of the easy-axis type (Ising anisotropy) or of the easy-plane type (XY anisotropy). The former means that the spins tend to orient parallel to a preferential direction while for the latter they orient in a plane. The physical properties of the chains are strongly influenced by the nature of the anisotropy. ... 

The architectural unit is interpreted as a synopsis, from juvenile to adult, and comprises the branch categories that are produced during that development. It is thus a summary of the branch potential of the plant. It can vary from a simple structure (e.g., a single monopodium without lateral branches) to more complex structures consisting of numerous axis types at different hierarchical levels. 

Reiteration is typically sympodial, and also may be monopodial. Reiteration may be full or partial. Full reiteration reproduces the basic repeated units of constrnction of mosses, inclnding all the axis types produced by any particular species, as well as any other structures (perigonia, perichaetia, etc.). In mosses this means reproduction of the primary modnle. The plants are made np of a series of connected primary modules and all the structures that are borne on them. Reiteration may be sympodial or monopodial.
