In summary, careful analysis of periodic PBE0 + D3 simulations of OH(aq) upends the conventional view that hemibonding disappears when hybrid functionals are employed. A distinctive feature in g(r O * O ) does indeed disappear in warmer water, only to re-emerge upon cooling to T = 310 K, but hemibonded configurations persist even at T = 370 K, hiding in plain sight beneath a much larger hydrogen-bonded feature in g(r O * O ).
