An ideal one-dimensional antiferromagnetic spin system observed in hydrogen-bonded napth [2,3-d] imidazol-2-yl nitronyl nitroxide crystal: the role of hydrogen bond
Article Abstract:
The synthesis, crystal structure, and magnetic properties of newly designed napth [2,3-d] imidazol-2-yl nitronyl nitroxide are described to examine the effects of ring extension on the crystal packing and magnetic behavior. The results conclude that space interaction between the O atoms of the nitroxide is predominant, by considering the identical magnetic data between the NH nondeuterated and deuterated samples.

Anomalous thermal behaviour of salicylsalicylic acid and evidence for a monotropic transition to a nematic phase
Article Abstract:
An anomalously strong heating rate dependence of the temperature of maximum intensity (Tmax) of the differential scanning calorimetry (DSC) clearing peak of salicylsalicyclic acid that is associated to the existence of a nematic phase between the crystal and the isotropic phase is reported. The results obtained from DSC, polarizing optical microscopy (POM) and X-ray diffractometry is discussed.

Low-temperature phase transition in a biphenyl-fullerene single crystal: a Raman study
Article Abstract:
Investigations are made by means of temperature-dependent vibrational spectroscopy, the properties of neutral single crystal of C(sub 60) intercalated with biphenyl. The Raman data depict phase transitions in 2P-C(sub 60) in several ways.
