Theoretical calculations on the OSiS molecule and its interstellar relevance
One of the most abundant elements in the universe is silicon, and several studies have already been performed on their silicate forms. Nevertheless, few species with the SiO bond have been detected in the interstellar space [1][2]. Recently, spectroscopic techniques have detected SiS in some interstellar clouds, and SiO in minor amounts. These two diatomic molecules can be related to a depletio...
متن کاملSuggestions for an interstellar C5H2 search
Laboratory detection of four isomers of C5H2 molecule have been reported by Travers et al. (1997), McCarthy et al. (1997), and Gottlieb et al. (1998). They suggested for detection of the ring-chain isomer of C5H2 (c-C5H2) in cosmic objects, as it is the most stable one in comparison to the others. Two transitions 313−212 and 303−202 at 19.147 GHz and 19.606 GHz, respectively, of c-C5H2 have bee...
متن کاملA Simple Theoretical Model for Prediction of Phase Inversion
Phase inversion in liquid-liquid dispersions corresponds to the transitional boundary between Oil-in-Aqueous dispersion and Aqueous-in-Oil dispersion. A theoretical model based on simple assumptions was proposed to predict phase inversion point, ambivalence region and the hysteresis effect of inversion. Experimental data from the literature were used to validate the model and results were c...
متن کاملTheoretical Prediction of a 443 Nm Transition: a Potential Carrier of a Diffuse Interstellar Band
The carriers of the diffuse interstellar bands (DIBs) is one of the longest standing problems in astronomical spectroscopy. This completely unattributed absorption spectrum stretches from the UV to near-IR and can be seen in multiple interstellar sightlines with the strongest features at 443 nm and 578 nm. Additionally, the number of known features grows with every observation. No known molecul...
متن کاملTheoretical prediction of new dipole-bound singlet states for anions of interstellar interest.
Anions that exhibit dipole-bound singlet states have been proposed as a potential class of molecules that may be identified in the interstellar medium. Using high-level coupled cluster theory, we have computed the dipole moments, electron binding energies, and excited states of 14 neutral radicals and their corresponding closed-shell anions. We have calibrated our methods against experimental d...
