The influence of the chalcogen atom in the allyl substituent series is illustrated by the comparison of the first four experimental ionization energies of allyl isocyanate 5,
The densities of the nematic and isotropic phases in equilibrium have been used in conjunction with a van der Waals theory of liquid crystals to provide information on mean
In the case when the both pyridinic and benzenic ring in the mesomorphic molecule are conjugated (compounds IIIa-d, Table 111) a certain increase of a mesophase
Cubic AuCu,-type compounds : The results of very low temperature specific heat measurements for 8 uranium and 2 neptunium compounds are given in table VI together
However, it may be noticed that for SX phases and particularly SA2 phases, the domain observed differs from the Cole and Cole distribution.. So, to
However, the Grandjean lines align parallel to each other and delimit domains in which the number of cholesteric layers is different whereas here, one or a few
At low temperature a transition towards an SA2 phase occurs and we see two sharp Bragg spots which correspond to the two first-orders of diffraction by a
