Optically active low-temperature inversion stabilised 1,2-dithiane by photolysis with circularly polarised light

• Optically active 1,2-dithiane has been produced in a hydrocarbon g ass at 77 K by photolysis with circularly polarised light. Its CD spectrum (above 270 nm) consists of a single symmetric component coinciding with the position of the low energy absorption band. The possibility of using the method to study any per se chiral but at room temperature statistically optically inactive molecule is stressed. A relation yielding Δϵ is presented.
