def calculate(self, T, method):
        r'''Method to calculate permittivity of a liquid at temperature `T`
        with a given method.

        This method has no exception handling; see `T_dependent_property`
        for that.

        Parameters
        ----------
        T : float
            Temperature at which to calculate relative permittivity, [K]
        method : str
            Name of the method to use

        Returns
        -------
        epsilon : float
            Relative permittivity of the liquid at T, [-]
