Isolation and Structure Elucidation of the Heterocumulene Anions [NCC‐L]− (L=CO, CS, N2)
Angewandte Chemie, Volume 137, Issue 13, March 24, 2025.The cumulated 5‐atomic cyanodiazomethanide [NCCNN]− and thioketenyl anion [NCCCS]− were synthesized from the metalated ylide and ketenyl anion, respectively. Both anions exhibit unexpected stability, but with notable structural differences. While the cyanodiazomethanide features a distinctly bent geometry, the thioketenyl anion was found to be linear ...

PRESTALINE: a package for simulation and analysis of molecular spectra of star forming regions
Open Astronomy, 2021 We present the PRESTALINE package, a novel tool to simulate and analyse spectra of star forming objects. PRESTALINE allows for a direct comparison of theoretical models with observations and simplifies an analysis of observed spectra.

Search of amino group in the Universe: 2-aminopyridine [PDF]
Serbian Astronomical Journal, 2015 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)
