Fulminic acid (HCNO) played a critical role in the early development of organic chemistry, and chemists have sought to discern structure characteristics this molecule its isomers for over 200 years. The mercurial nature extremely flat H-C-N bending potential fulminic acid, with nearly vanishing harmonic vibrational frequency at linearity, remains enigmatic refractory electronic theory, as dramatic variation both orbital basis set electron correlation method is witnessed. To solve problem...
Abstract Twistane, C 10 H 16 , is a classic D 2 ‐symmetric chiral hydrocarbon that has been studied for decades due to its fascinating stereochemical and thermodynamic properties. Here we propose analyze in detail the contiguous linear extension of twistane with ethano (ethane‐1,2‐diyl) bridges create new chiral, nanotube called polytwistane. Polytwistane, (CH) n same molecular formula as polyacetylene but composed purely C(sp 3 )H units, all which are chemically equivalent. The...
The ground electronic state of C(BH)2 exhibits both a linear minimum and peculiar angle-deformation isomer with central B-C-B angle near 90°. Definitive computations on these species the intervening transition have been executed by means coupled-cluster theory including single double excitations (CCSD), perturbative triples (CCSD(T)), full quadruples (CCSDT(Q)), in concert series correlation-consistent basis sets (cc-pVXZ, X=D, T, Q, 5, 6; cc-pCVXZ, X=T, Q). Final energies were pinpointed...
As one of two planetary objects (other than Earth) that have solid surfaces, thick atmospheres, and astrobiological significance, Titan, like Mars, merits ongoing study with multiple spacecraft.We propose a Titan orbiter dedicated to geophysics, geology, atmospheric science be added the New Frontiers menu for coming decade.
<p>Spectra taken by the Cassini Composite Infrared Spectrometer (CIRS) can be used to retrieve vertical temperature profiles and mole fractions of trace gases in 100 500 km region Titan’s atmosphere. The retrieved fractions, along with fraction predictions from a photochemical model, infer dynamics atmosphere if it shown that transport life-time is shorter than life-time. In addition, chemical evolution atmosphere, haze formation rate, etc. deduced comparing model...
