Search of amino group in the Universe: 2-aminopyridine

In search for life in the Universe, scientists are interested in identification of molecules having amino (-NH2) group in the interstellar space. The aminoacetonitrile (NH2CH2CN), which is precursor of the simplest amino acid glycine (NH2CH2COOH), is identified near the galactic center. The...

description In search for life in the Universe, scientists are interested in identification of molecules having amino (-NH2) group in the interstellar space. The aminoacetonitrile (NH2CH2CN), which is precursor of the simplest amino acid glycine (NH2CH2COOH), is identified near the galactic center. The 2-Aminopyridine (H2NC5H4N) is of interest for scientists as it has a close association with life on the earth. Based on spectroscopic studies, we have calculated intensities of 2-Aminopyridine lines due to transitions between the rotational levels up to 47 cm−1 and have found a number of lines which may help in its identification in the interstellar medium. Frequencies of some of these transitions are found close to those detected in the envelope of IRC +10216 that are not assigned to any of the known species.
