Enantiomer-selective UV photolysis of temperature-controlled protonated tryptophan on a chiral crown ether was examined using a tandem mass spectrometer containing a temperature-variable 22-pole ion trap. The results show that enantiomer-selective photolysis of amino acids on chiral substances might induce an excess of L-amino acids in interstellar molecular clouds as they relate to the origin of homochirality in biological molecules.
