摘要: A selection of five proteinogenic amino acids, namely glycine, isoleucine, phenylalanine, tyrosine and tryptophan were studied in the mid-infrared far-infrared with purpose to facilitate search identification these astrobiological astrochemical relevant molecules space environments. The molar extinction coefficients ({\epsilon}) all mid- bands determined as well integrated absorptivities ({\psi}). spectra selected acids recorded also at three different temperatures from -180{\deg}C ambient temperature +200{\deg}C. We measure wavelength shift infrared caused by and, for most or temperature-sensitive bands, a series linear equations relating position temperature. Such may provide estimates once detected astrophysical objects reported values {\epsilon} {\psi}, it will be possible estimate relative abundance
