\tablefoot{The first column reports the generic formula of
    the molecules, ordered in increasing molecular weight. The next
    two columns report the most stable isomer with its dipole moment;
    fourth and fifth columns report the less abundant isomer(s) with
    the relevant dipole moment; Cols.~6 to~8 report the relative
stability with respect to the most stable (Col.~2)  computed using the  three different methods discussed in Sect.~2.
