Abstract

The success of future missions to search for life on ocean/icy worlds or investigate organic molecule rich planetary atmospheres depends on the ability to accurately identify and quantify biomarkers in the presence of a mixture of molecules. Mass spectrometry alone is insufficient to unambiguously identify biomarkers due to the existence of isomers, but combined with infrared spectroscopy additional information can be extracted. Amino acids are a prime target in the search for biomarkers due to their importance in terrestrial biology. Here, we present cryogenic gas-phase infrared spectra of protonated valine and some chemical analogs. We assign spectral features using density functional theory calculations, and we discuss prospects for chemical identification.
