Hydrogen cyanide (HCN), also known as prussic acid, plays a crucial role in the study of space and exoplanets, as it has been observed in the atmospheres of certain planets and moons in our solar system. HCN has also been detected in various extraterrestrial environments, including comets, and meteorites. The presence of HCN in these environments suggests that the chemistry involving HCN could be relevant to the origin of life on other celestial bodies as well.
we decided to construct an extensive database of empirical rovibrational energy levels, based on spectral features measured under high resolution, for all the isotopologues of hydrogen cyanide involving the H, D, 12C, 13C, 14C, 14N, and 15N isotopes. All the emperical energy leveels for the first 8 most abundant isotopologues of HCN are going to be calculated (124, 134, 125, 135, 224, 234, 235, 225).
