Parallel with interest in the \(\mathrm{p}-\mathrm{V}-\mathrm{T}\) properties of water(\(\ell\)), enormous interest has been shown in the relative permittivity of water(\(\ell\)) as a function of \(\mathrm{T}\) and \(\mathrm{p}\). Owen and Brinkley [1] showed that a type of Tait equation could be used to express the \(\mathrm{T}-\mathrm{p}\) dependence of the relative permittivity of many liquids, including water(l). In 1980, Uematsu and Franck reviewed published information concerning the permittivity of water(\(\ell\)) and steam published over a period of 100 years [2,3].

A careful determination was reported by Deul in 1984 [4]. At \(298.15 \mathrm{~K}\) and ambient pressure, the relative permittivities of water(\(\ell\)) and \(\mathrm{D}_{2}\mathrm{O}(\ell\)) are 78.39 and 78.06 respectively [5]. A report by Owen and co-workers in 1961 stated a value of 78.358 for water(\(\ell\)) at \(298.15 \mathrm{~K}\). Bradley and Pitzer [7] survey published relative permittivities of water(\(\ell\)) over an extensive temperature range.
