Authors: Valdes, Alvaro; Prosmiti, Rita Journal: JOURNAL OF CHEMICAL PHYSICS Publication date: 2024/05/14 DOI: 10.1063/5.0210866 Abstract: We present new results on the underlying guest-host interactions and spectral characterization of a CO2 molecule confined in the cages of the sI clathrate hydrate. Such types of porous solids raise computational challenges, as they are of practical [...]

Authors: Martinez-Gil, Daniel; Bargueno, Pedro; Miret-Artes, Salvador Journal: ENTROPY Publication date: 2024/06/01 DOI: 10.3390/e26060456 Abstract: In this review, the concepts of quantum tunneling and parity violation are introduced in the context of chiral molecules. A particle moving in a double well potential provides a good model to study the behavior of chiral molecules, where [...]

Authors: Cernicharo, J.; Cabezas, C.; Agundez, M.; Fuentetaja, R.; Tercero, B.; Marcelino, N.; de Vicente, P. Journal: ASTRONOMY & ASTROPHYSICS Publication date: 2024/08/07 DOI: 10.1051/0004-6361/202451256 Abstract: We present the detection of the free radicals NC3S and HC3S towards TMC-1 with the QUIJOTE line survey. The derived column densities are (1.4 +/- 0.2)x10(11) for NC3S and [...]
