Solvents are arranged according to thermal conductivity. Christian Reichardt's spectroscopic solvent polarity scale, labeled ET(30), is based on the solvatochromic charge-transfer absorption shift for ET-30 (a large heteronuclear polycyclic aromatic). See Christian Reichardt, Chemical Reviews, 1994, 94, 2319-2358 for details. Thermal conductivity (k), heat capacity (CP @ 25C), thermal diffusivity (DT), temperature-dependent refractive index, (dn/dT), and volume expansion coefficient (b=(1/V)(dV/dT)), are from several sources; as compiled in Photothermal Spectroscopy Methods for Chemical Analysis, Wiley, 1996, with preference to thermodynamic values specified in David R. Lide, CRC Handbook of Chemistry and Physics, 76th Ed, 1995. (dn/dT) for toluene, benzene, carbon disulfide, and chloroform are from Hassan El-Kashef, Rev. Sci. Instrum. 69, 1243 1998. Formula weight (FW), refractive index (n, @ 20C, sodium D), and density (r) are from the 1999 Aldrich Chemical Company catalog. Acoustic velocity (v) are from Specialty Engineering Associates (SEA), Soquel, California (USA). Molar refractivities (Rm) are based on refractive indicies and molar densities (r/FW). Dielectric constants (e), and their temperature dependences are from the CRC Handbook of Chemistry and Physics, 76th Ed, 1995, or calculated based on refractive index and/or it's temperature dependence.
