Collisional excitation of PO by -H
F. Tonolo, L. Bizzocchi, V. M. Rivilla +3
We report the derivation of rate coefficients for the rotational (de-)excitation of PO induced by collisions with H. The calculations were performed on a four-dimensional p…
Hyperfine resolved rate coefficients of HC17O+ with H2 (j = 0)
Francesca Tonolo, François Lique, Mattia Melosso +2
The formyl cation (HCO+) is one of the most abundant ions in molecular clouds and plays a major role in the interstellar chemistry. For this reason, accurate collisional rate coeff…
Precursors of the RNA-world in space: Detection of ()-1,2-ethenediol in the interstellar medium, a key intermediate in sugar formation
Víctor M. Rivilla, Laura Colzi, Izaskun Jiménez-Serra +20
We present the first detection of ()-1,2-ethenediol, (CHOH), the enol form of glycolaldehyde, in the interstellar medium towards the G+0.693-0.027 molecular cloud located in…
An improved study of HCO+ and He system: interaction potential, collisional relaxation and pressure broadening
F. Tonolo, L. Bizzocchi, M. Melosso +4
In light of its ubiquitous presence in the interstellar gas, the chemistry and reactivity of the HCO+ ion requires special attention. The availability of up-to-date collisional dat…
Formation of phosphorus monoxide (PO) in the interstellar medium: insights from quantum-chemical and kinetic calculations
Juan García de la Concepción, Cristina Puzzarini, Vincenzo Barone +2
In recent years, phosphorus monoxide (PO) -- an important molecule for prebiotic chemistry -- has been detected in star-forming regions and in the comet 67P/Churyumov-Gerasimenko.…
Methanimine as a key precursor of imines in the interstellar medium: the case of propargylimine
Jacopo Lupi, Cristina Puzzarini, Vincenzo Barone
A gas-phase formation route is proposed for the recently detected propargylimine molecule. In analogy to other imines, such as cyanomethanimine, the addition of a reactive radical…
The Role of State-of-the-Art Quantum-Chemical Calculations in Astrochemistry: Formation Route and Spectroscopy of Ethanimine as a Paradigmatic Case
Carmen Baiano, Jacopo Lupi, Nicola Tasinato +2
The gas-phase formation and spectroscopic characteristics of ethanimine have been re-investigated as a paradigmatic case illustrating the accuracy of state-of-the-art quantum-chemi…
The quest for a plausible formation route of formyl cyanide in the interstellar medium: a state-of-the-art quantum-chemical and kinetic approach
F. Tonolo, J. Lupi, C. Puzzarini +1
Interstellar complex organic molecules (iCOMs) are assumed to be mainly formed on dust-grain surfaces. However, neutral gas-phase reactions in the interstellar medium (ISM) can pla…
A Systematic Study on the Absorption Features of Interstellar Ices in Presence of Impurities
Prasanta Gorai, Milan Sil, Ankan Das +12
Spectroscopic studies play a key role in the identification and analysis of interstellar ices and their structure. Some molecules have been identified within the interstellar ices…
