@property<EOL><INDENT>def permittivity(self):<DEDENT>
return self.Permittivity(self.T)<EOL>
r'''Relative permittivity (dielectric constant) of the chemical at its 
        current temperature, [dimensionless].

        For calculation of this property at other temperatures,
        or specifying manually the method used to calculate it, and more - see
        the object oriented interface :obj:`thermo.permittivity.Permittivity`;
        each Chemical instance creates one to actually perform the calculations.

        Examples
        --------
        >>> Chemical('toluene', T=250).permittivity
