Reaction of atomic hydrogen and carbon disulfide: infrared spectra of HSCS and HSHCS in solid argon
TL;DR: Matrix infrared spectroscopy has been used to characterize the cocondensation reaction products of H atoms and CS 2 in solid argon at 12 K as discussed by the authors, and the major product bands at 12752 and 12278 cm -1 were characterized by photolysis with 320-1000-nm radiation and reappearance on annealing to 18 K to allow diffusion and reaction of trapped H atoms Deuterium, 13 C, and 34 S isotopic data were used to identify the HSCS radical
Journal ArticleDOI
The vibrational frequencies of cao2, sco2, and tio2 : a comparison of theoretical methods
TL;DR: In this article, the vibrational frequencies of several states of CaO2, ScO2 and TiO2 are computed using density functional theory (DFT), the Hartree-Fock approach, second-order Moller-Plesset perturbation theory (MP2), and the complete-active-space self-consistent field theory.
Journal ArticleDOI
Infrared spectra of CH2=M(H)NC, CH3-MNC, and eta2-M(NC)-CH3 produced by reactions of laser-ablated group 5 metal atoms with acetonitrile.
Han-Gook Cho,Lester Andrews +1 more
TL;DR: The Group 5 metal methylidene isocyanides exhibit more agostic distortion than the Zr counterparts and are comparable to the previously studied Group 5Metal methylidenes hydrides and halides.
Journal ArticleDOI
3d-Metal monocarbonyls MCO, MCO+, and MCO− (M=Sc to Cu): comparative bond strengths and catalytic ability to produce CO2 in reactions with CO
TL;DR: In this article, the electronic and geometrical structures of 3d-metal monocarbonyls MCO (M=Sc to Cu), the MCO − anions and MCO + cations are computed using the density functional theory with generalized gradient approximation for the exchange-correlation potential.
