Susceptibility molar

Lithium oxides of Pu, magnetic measurements and reciprocal molar susceptibility vs. 

The dimensionless proportionality factor % is the magnetic susceptibility. The magnetization and consequently also the susceptibility depend on the number of orientable particles in a given volume. A volume-independent, material-specific magnitude is the molar susceptibility xmoi...

The temperature dependence of the molar susceptibility of a paramagnetic substance follows the Curie-Weiss law (if the magnetic field is not too strong) ... 

A hysteresis cycle in the molar susceptibility measurements has been observed for [Ni2(Medpt)2(N3)2(/r-N3)2] (883). This has been ascribed to a phase transition caused by an asymmetrization process of the rhombus-like centrosymmetric [Ni-(N3)2-Ni] core that occurs with falling temperature. The asymmetrization transition can be explained in terms of a second-order Jahn-Teller distortion, taking into account the local symmetry of the dinuclear [Ni-(N3)2-Ni] entity (D2h, rhombic symmetry) before the arrangement.2128...

Another quantitative characteristic of the magnetic manifestation of aromaticity is represented by the exaltation of the total magnetic susceptibility A (68JA811 75MI2). For conjugated compounds, this parameter is given by the difference between Xm and Xm standing, respectively, for the experimentally measured molar susceptibility and the molar susceptibility... 

The magnetic moment, m, is a term used to quantify the magnetic properties of a substance. It is not measured directly, but is obtained from the measured molar susceptibility to which it is related, i. e.

The molar susceptibility of the sample, can be obtained from x by applying Eq. 11.35. 

The next step is to connect the macroscopic susceptibility to individual molecular moments and finally to the number of unpaired electrons. From classical theory, the corrected or paramagnetic molar susceptibility is related to the permanent paramagnetic moment of a molecule, y. by ...

By multiplying the specific susceptibility of a compound by its molecular weight, we can obtain the molar susceptibility, xM ... 

The measurement x or Xm> or perhaps M, is the one usually carried out. For chemical applications it is usual to relate these to more relevant quantities. The molar susceptibility, xm is... 

The volume susceptibility of [TCNQ-TTF], %s, thus calculated is then converted to its molar susceptibility, %m, by multiplying the molecular weight of 408 for [TCNQ-TTF] and dividing by the crystal density of 1.6 gm/cc. The results are in excellent agreement. 

The coefficients a and b (see Table 3.2) take into account the restrictions in spin dimensionality. For a = b= 1, the Heisenberg model with isotropic exchange interaction and isotropic susceptibility results. The combination of a = 1 and b = 0 yields the strictly anisotropic Ising model, in which the orientation of the spins is restricted to the z-axis. Consequently, the susceptibility is strongly orientation dependent and one needs to differentiate between x" in the direction of the z-axis ( easy axis ) and x perpendicular to z. The molar susceptibilities are then related as...
