Reconciling spectroscopy with dynamics in global potential energy surfaces: the case of the astrophysically relevant SiC$_{2}$

Autor: Rocha, C. M. R., Linnartz, H., Varandas, A. J. C.

SiC$_2$ is a fascinating molecule due to its unusual bonding and astrophysical importance. In this work, we report the first global potential energy surface (PES) for ground-state SiC$_2$ using the combined-hyperbolic-inverse-power-representation (CH

High-level ab initio quartic force fields and spectroscopic characterization of C$_{2}$N$^{-}$

Autor: Rocha, C. M. R., Linnartz, H.

While it is now well established that large carbon chain species and radiative electron attachment (REA) are key ingredients triggering interstellar anion chemistry, the role played by smaller molecular anions, for which REA appears to be an unlikely

Theoretical studies of carbon isotopic fractionation in reactions of C with C$_{2}$: dynamics, kinetics, and isotopologue equilibria

Autor: Rocha, C. M. R., Linnartz, H.

Publikováno v: A&A 647, A142 (2021)

Our current understanding of interstellar carbon fractionation hinges on the interpretation of astrochemical kinetic models. Yet, the various reactions included carry large uncertainties in their (estimated) rate coefficients, notably those involving

Ostwald ripening for air bubbles and decompression illness: phenomenological aspects in diving

Autor: Del Cima, O. M., Rocha, C. M., Teixeira, A. V. N. C., Wienke, B. R.

The Ostwald ripening phenomenon for gas bubbles in a liquid consists mainly in gas transfer from smaller bubbles to larger bubbles. An experiment was carried out in which the Ostwald ripening for air bubbles, in a liquid fluid with some rheological p
