Rules of 'H2O'

There are a number of water (H2O) molecules in the grid, each composed of two Hydrogen(H) atoms and one Oxygen(O) atom. Atoms in a molecule connect each other either in a straight line or in a 90-deg angle. Locate the Oxygen atoms, which do not touch each other, not even diagonally.
