## Abstract The photochemical reactions of (__E__)βΞ±βionone (**1**) and its photoproducts have been reβexamined. Upon irradiation with Ξ» 254 and 313 nm a sequence of photoβreactions takes place: initially (__Z__)βΞ±βionone (**2**) is formed and subsequently (__E__)β and (__Z__)β__retro__βΞ±βionone (*
