This is the expression of the uncoupled Hartree Fock polarizability per unit cell [33], Since in this case, there is no coupling between the different vertical transitions, the coupling, and thus the matrices Ai and B, are responsible for the field-induced electron reorganizational effects. 

A more general point is that the maximum spin is often not attained due to antiferromagnetic coupling. In Gd(III) systems, Msat can usually be attained in moderate fields, whereas when transition metals are involved the spin state can be less than the maximum possible. Here, Gd(III)4Cu(II)8 has a spin of S = 18, the maximum possible (albeit field induced). 

The atomic properties satisfy the necessary physical requirement of paralleling the transferability of their charge distributions - atoms that look the same in two molecules contribute identical amounts to all properties in both molecules, including field-induced properties. Thus the atoms of theory recover the experimentally measurable contributions to the volume, heats of formation, electric polarizability, and magnetic susceptibility in those cases where the group contributions are found to be transferable, as well as additive additive [4], The additivity of the atomic properties coupled with the observation that their transferability parallels the transferability of the atom s physical form are unique to QTAIM and are essential for a theory of atoms in molecules that purports to explain the observations of experimental chemistry. 

As the isoquinoline molecule reorients in the order listed above, the absorption of infrared radiation by the in-plane vibrational modes would be expected to increase, while that of the out-of-plane modes would be predicted to decrease (in accordance with the surface selection rule as described above). In the flat orientation there is no component of the dipole moment perpendicular to the surface for the in-plane modes, and under the surface selection rule these modes will not be able to absorb any of the incident radiation. However, as mentioned above, infrared active modes (and in some cases infrared forbidden transitions) can still be observed due to field-induced vibronic coupled infrared absorption (16-20). We have determined that this type of interaction is present in this particular system. 

One can see that E is a vector, whereas B is a pseudovector, that is, E changes sign upon inversion of the coordinate system, while B remains unchanged. As a consequence, electric-field-induced interactions couple states of different parity, while interactions induced by the magnetic field conserve parity. Thus, parity remains a good quantum number for quantum systems in a magnetic field. 

The DNA hybridization of an Au NP-DNA hybrid can be controlled through inductive coupling of a radiofrequency (1 GHz) electromagnetic field to the Au NP (1.4 nm), which acts as an antenna, increasing the local temperature of the bound DNA and inducing denaturation. The switch on-off of the electromagnetic field induces a reversible denaturation-rehybridization of the DNA double-helix [196].
