  We have investigated the hydrogen-bonded structures in liquid methanol and a
7:3 mole fraction aqueous solution using classical Molecular Dynamics
simulations at 298K and ambient pressure. We find that, in contrast to recent
predictions from X-ray emission studies, the hydrogen-bonded structure in
liquid methanol is dominated by chain and small ring structures. In the
methanol-rich solution, we find evidence of micro-immiscibility, supporting
recent conclusions derived from neutron diffraction data.
