Molecular clusters and correlations in liquid methanol at room temperature

The analysis of x-ray diffraction data of liquid methanol at room temperature reveals a distinct possibility of the presence of hexamer molecular clusters due to intermolecular hydrogen bonding. On the assumption of hexamer domination in the structure, the center structure is derived, which in turn reproduces closely the available data on neutron diffraction and computer simulation for this system. The center–center correlations show special features of bonded structure.
