r'''Estimates the thermal conductivity of organic liquid substances
    according to the method of [1]_.

    .. math::
        \lambda^* = \frac{\lambda\cdot V_c^{2/3}\cdot T_c\cdot \text{MW}^{0.5}}
        {(k\cdot T_c)^{1.5}\cdot N_A^{7/6}}

        \lambda^* = \frac{2}{3}\left(n_a + 40\sqrt{1-T_r}\right)

    Parameters
    ----------
    T : float
        Temperature of the fluid [K]
    M : float
        Molecular weight of the fluid [g/mol]
    Tc : float
        Critical temperature of the fluid [K]
    Vc : float
        Critical volume of the fluid [m^3/mol]
    atoms : dict
        Dictionary of atoms and their counts, [-]

    Returns
    -------
    kl : float
        Estimated liquid thermal conductivity [W/m/k]

    Notes
    -----
    In the equation, all quantities must be in SI units but N_A is in a kmol
    basis and Vc is in units of (m^3/kmol); this is converted internally.
