Research Abstract

In order to investigate structure and reactivity of temperature-controlled hydrogen-bonded cluster ions, a photodissociation spectrometer containing a spray ionization source, a temperature-variable 22-pole ion trap (8-400 K), and a reflectron time-of-flight mass spectrometer was developed. Enantiomer-selective ultraviolet photolysis of temperature-controlled protonated tryptophan on a chiral crown ether was examined as they relate to the origin of homochirality in biological molecules. The results show that enantiomer-selective photolysis on chiral substances might play important roles in inducing an excess of L-amino acids in interstellar molecular clouds.
