T Reduced temperature

T = reduced temperature of the mixture P = reduced pressure of the mixture... 

T = Reduced temperature of mixture P,n, = Reduced pressure of mixture = Compressibility factor of mixture... 

P = reduced pressure p = reduced density T = reduced temperature... 

Fig. 17. Temperature dependence of the orientational order parameters of the cholestane spin probes in various liquid crystal systems. The order parameters refer to side chain polymer I ( , M = 14000), side chain polymer 2 (O, M, = 14000) and the low molecular weight analogue 5(A). Dashed lines indicate different phase transitions (see Table 1). T = reduced temperature...

Fig, 28. Temperature dependence of conformational order of main chain polymers and low molecular weight analogues, expressed in terms of segmental order parameters S., 2 at various chain segments. Open symbols refer to the a-positions, while full symbols denote the 5-positions. The order parameters refer to main chain polymer 4 (0> ), dimer 7 ( ) and monomer 8 (A). Dashed lines mAk Xe different phase transitions. T = reduced temperature... 

The properties T (reduced temperature) and 5 (polarity parameter) have the same meaning as in Paragraph 1 and can therefore be calculated using the following equations ... 

AE( qp = heat of vaporization T, = reduced temperature, T/Tc A = correlation constant...
