Appendix A
Details on the samples
This appendix gives an overview of the different properties of the liquids we have
mainly studied. We give the details on the samples and where they have been
acquired. The appendix moreover contains the references and/or calculations of
the fragilities, scaling exponent, x, T g (P), and the equation of state, which are used
throughout the thesis. The fragilites m P and m ρ as well as the exponent x =
are defined in chapter 3.

A.1 Cumene
Cumene is a popular name for isopropylbenzene (1-methyl ethylbenzene), which is
a benzene ring with one side group consisting of a carbon atom with two methyl
groups attached. The sum formula is C 9 H 12 and the density at ambient conditions
is 0.864 g/mol.
The sample used is from Sigma-Aldrich. The viscosity as a function of temperature
is reported by Ling and Willard [1968] at temperatures from 130 K to 150 K and
by Barlow et al. [1966] in the range 150 K to 303 K. Barlow et al. [1966] moreover
report the density as a function of temperature at atmospheric pressure in the range
150 K to 320 K. The temperature dependence of the density is found to be linear in
this range, and we assume that this dependence is continued down to 126 K, which
is the lowest temperature of interest. The density as a function of pressure has been
measured by Bridgman [1949] at room temperature from atmospheric pressure up
