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. |
