A selection of five proteinogenic amino acids-glycine, isoleucine, phenylalanine, tyrosine, and tryptophan-were studied in the mid-infrared and in the far-infrared with the purpose to facilitate the search and identification of these astrobiologically and astrochemically relevant molecules in space environments. The molar extinction coefficients (ɛ) of all mid- and far-infrared bands were determined as well as the integrated molar absorptivities (ψ). The mid-infrared spectra of the five…

Infrared spectroscopy and integrated molar absorptivity of C60 and C70 fullerenes at extreme temperatures
The detection of C60 and C70 fullerenes in young planetary nebulae and in reflection nebulae suggests that these molecules are more common in certain astrophysical environments than previously

Solid state radiolysis of amino acids in an astrochemical perspective
Abstract The aliphatic amino acids l -alanine and l -leucine and the aromatic amino acids l -phenylalanine, l -tyrosine and l -tryptophan were irradiated in the solid state to a dose of 3.2 MGy. The
An infrared study of solid glycine in environments of astrophysical relevance.
Different spectral features are suggested as probes for the presence of glycine in astrophysical media, depending on its form (neutral or zwitterionic), their temperature and composition.
Radiolysis and radioracemization of 20 amino acids from the beginning of the Solar System
A series of chiral amino acids in the levo form used in the current terrestrial biochemistry were irradiated in the solid and dry state with γ-radiation to a dose of 3.2 MGy which is the dose
Vibrational spectroscopic studies of Isoleucine by quantum chemical calculations.
A combined experimental and theoretical study on molecular structure, vibrational spectra and NBO analysis of Isoleucine (2-Amino-3-methylpentanoic acid) and the formation of hydrogen bond was investigated.
Amino acids in comets and meteorites: stability under gamma radiation and preservation of the enantiomeric excess
This study adds experimental support to the suggestion that amino acids were formed in the interstellar medium and in chiral excess and then were incorporated into comets and asteroids at the epoch of Solar system formation.
Amino acids formed from the UV/EUV irradiation of inorganic ices of astrophysical interest
Abstract An experiment where a H 2 O:CO 2 :NH 3  = 1:1:1 ice mixture was irradiated using the ultraviolet/extreme ultraviolet (UV/EUV) light provided by a synchrotron beam in the broad 4–20 eV
Importance of entropy in the conformational equilibrium of phenylalanine: a matrix-isolation infrared spectroscopy and density functional theory study.
Phenylalanine can be considered a notable example of a molecule where entropy plays an essential role in determining the relative abundance of the possible low-energy conformational states and then, the thermodynamics of the compound, even at moderate temperatures.
