Interstellar tryptophan revisited
Abstract
A recent assignment of the amino acid tryptophan to infrared emission lines in the gas of the IC 348 star cluster is re-examined. A comparison of spectra from the Spitzer Telescope to laboratory data shows that there is no firm support for the tryptophan assignment. Suggestions are made for future observational searches for tryptophan and for supporting laboratory work.
