Irradiation of 4-methoxystyrene (1) in zeolite NaY under vacuum, dry oxygen, and wet air yielded dimers and oxygenation products dependent on the atmosphere and co-adsorbed water. Head-to-head c/s-and trans-cyclobutane dimers of I were produced at the isomer ratio of 91/9 under vacuum through excime
