A study of the orientational dynamics of liquid pterphenyl in the time domain by means of transient optical Kerr effect spectroscopy is presented. The orientational relaxation is measured at several temperatures above the liquid-plastic phase transition, following the decay from a few hundreds offs
## Methods of measurement of the phase transition temperatures in physical molecular gels are analyzed. The "falling ball technique, NMR, and rheology are compared. Temperature versus concentration phase diagrams can be easily obtained, and the reliability and workability of the methods are discus
Transition to a ferromagnetic long-range ordered state was found at 0.60 Kin the orthorhombic Pphase crystal ofg-nitrophenyl nitronyl nitroxide (or 2-(4'-nitrophenyl)-4,4,5,5-tetramethyl-4,5dihydro-lH-imidazol-l-oxyl-3-N-oxide in the IUPAC nomenclature). This finding follows our recent discovery of
The UV absorption spectrum of a TP smgle crystal IS measured between 297 and 77 K. The UV spectrum shifts to hyhcr encgy as the temperature falls. The temperature dependence of the UV absorption spectrum mdrcates that a disphcwe transltlon occurs rather than an order-disorder one III a TP crystal.
