The water structure around neopentane molecules is quantified by computing the pair correlation (g(r)). Figure represents g(r) between the center of masses of neopentane and water. When Garcia's model of TMAO employed, the water density in the first solvation shell of neopentane follows the following order water-urea-TMAO> water-urea> water-TMAO > water. A completely different order is found when Netz's TMAO force field is used. The order is water-urea>water-TMAO~water> water-urea-TMAO.
