One hand clapping : Based on solid‐state circular dichroism data, the leucine (π*, π 1 )‐electronic transition is excited with right circularly polarized synchrotron radiation ( r ‐CPSR) at 182 nm (see scheme). This treatment induced an enantiomeric excess of 2.6 % of D ‐leucine. The results support the assumption that interstellar asymmetric photoreactions are capable of inducing significant enantiomeric enrichments in solid‐state amino acids.
