These processes are of fundamental importance in initiating a 10 5 solar masses per year (22, 23). Pulsations from the central chain of chemical reactions leading eventually to the formation of star may initiate shocks, which (photo)fragment the circumstellar — organosilicon molecules among them key precursors to silicon car- materials (24, 25). These nonequilibrium conditions cause tem- — bide grains in the circumstellar shell contributing critically to the peratures of 3,500 K or above (19) and lead to highly reactive galactic carbon and silicon budgets with up to 80% of the ejected metastable fragments such as electronically excited silicon atoms, materials infused into the interstellar medium.

  • Rotational Spectroscopy of the Isotopic Species of Silicon Monosulfide, Sisw
    PAPER www.rsc.org/pccp | Physical Chemistry Chemical Physics Rotational spectroscopy of the isotopic species of silicon monosulfide, SiSw H. S. P. Mu¨ller,*ab M. C. McCarthy,cd L. Bizzocchi,e H. Gupta,cdf S. Esser,g H. Lichau,a M. Caris,a F. Lewen,a J. Hahn,g C. Degli Esposti,e S. Schlemmera and P. Thaddeuscd Received 2nd January 2007, Accepted 23rd January 2007 First published as an Advance Article on the web 20th February 2007 DOI: 10.1039/b618799d Pure rotational transitions of silicon monosulfide (28Si32S) and its rare isotopic species have been observed in their ground as well as vibrationally excited states by employing Fourier transform microwave (FTMW) spectroscopy of a supersonic molecular beam at centimetre wavelengths (13–37 GHz) and by using long-path absorption spectroscopy at millimetre and submillimetre wavelengths (127–925 GHz). The latter measurements include 91 transition frequencies for 28Si32S, 28Si33S, 28Si34S, 29Si32S and 30Si32Sinu = 0, as well as 5 lines for 28Si32Sinu = 1, with rotational quantum numbers J00 r 52. The centimetre-wave measurements include more than 300 newly recorded lines. Together with previous data they result in almost 600 transitions (J00 =0 and 1) from all twelve possible isotopic species, including 29Si36S and 30Si36S, which have fractional abundances of about 7 Â 10À6 and 4.5 Â 10À6, respectively. Rotational transitions were observed from u = 0 for the least abundant isotopic species to as high as u = 51 for the main species. Owing to the high spectral resolution of the FTMW spectrometer, hyperfine structure from the nuclear electric quadrupole moment of 33S was resolved for species containing this isotope, as was much smaller nuclear spin-rotation splitting for isotopic species involving 29Si.

    ARTICLE Designing Isoelectronic Counterparts to Layered Group V Semiconductors Zhen Zhu, Jie Guan, Dan Liu, and David Toma´nek* Physics and Astronomy Department, Michigan State University, East Lansing, Michigan 48824, United States ABSTRACT In analogy to IIIÀV compounds, which have significantly broadened the scope of group IV semiconductors, we propose a class of IVÀVI compounds as isoelectronic counterparts to layered group V semiconductors. Using ab initio density functional theory, we study yet unrealized structural phases of silicon monosulfide (SiS). We find the black-phosphorus-like R-SiS to be almost equally stable as the blue-phosphorus-like β-SiS. Both R-SiS and β- SiS monolayers display a significant, indirect band gap that depends sensitively on the in-layer strain. Unlike 2D semiconductors of group V elements with the corresponding nonplanar structure, different SiS allotropes show a strong polarization either within or normal to the layers. We find that SiS may form both lateral and vertical heterostructures with phosphorene at a very small energy penalty, offering an unprecedented tunability in structural and electronic properties of SiS-P compounds. KEYWORDS: silicon sulfide . isoelectronic . phosphorene . ab initio . electronic band structure wo-dimensional semiconductors of monosulfide (SiS).

We identified 84 molecular line transitions from 17 species and their isotopo- logues. The molecular gas distribution of these lines mainly peaks in the continuum position of W51 North, and has a small tail extending to the west, probably associ- ated with W51 d2. In addition to the commonly detected nitrogen and oxygen-bearing species, we detected a large amount of transitions of the Acetone (CH3COCH3) and Methyl Formate (CH3OCHO), which may suggest that these molecules are present in an early evolutionary stage of the massive stars. We also found that W51 North is an ethanol-rich source. There is no obvious difference in the molecular gas distributions between the oxygen-bearing and nitrogen-bearing molecules.

  • In the Interstellar Medium, Cosmic Rays Comprised Mostly of High-Energy
    In the interstellar medium, cosmic rays comprised mostly of high-energy protons can drive fast non-thermal reactions in the ice mantles covering microscopic dust grains. Illustrated here is such a collision, highlighting the tracks (shown in red) of both the cosmic ray and "secondary electrons" that are formed in the ice. This track was generated using the CIRIS program (Shingledecker et al., 2017). ON COSMIC RAYS IN ASTROCHEMICAL MODELS Christopher Nelson Shingledecker Virginia Beach, Virginia B.Sc. Chemistry with Highest Distinction University of Virginia, 2013 A Dissertation Presented to the Graduate Faculty of the University of Virginia in Candidacy for the Degree of Doctor of Philosophy Department of Chemistry University of Virginia April 2018 ii ⃝c Copyright by Christopher Nelson Shingledecker All rights reserved May 12, 2018 iii ABSTRACT OSMIC rays are known to have significant physicochemical impact on interstellar regions (Indriolo and McCall, 2013). For example, even in the very first astro- chemical modeling work of Herbst and Klemperer (1973), cosmic rays were shown to drive the gas-phase chemistry of molecular clouds through the ion- + Cization of H2 and subsequent formation of H3 . Later, Prasad and Tarafdar (1983) demon- strated that cosmic rays - and the secondary electrons they generate - could collisionally excite the Lyman and Werner bands of H2, leading to the formation of internal UV pho- tons in dense regions where the external interstellar UV radiation field is quickly attenu- ated. However, despite the central role that the ionization and excitation of H2 currently plays in astrochemical models, extending the treatment of these types of interactions to other species has proven challenging thanks to both the complexity and variety of under- lying microscopic processes, which has stymied the development of suitable theoretical and computational techniques.
