1 Miller, Joel StevenInvolvement of titanocene and related species in the reduction of dinitrogen and olefinsSummary Four sequential products have been spectrally detected in the reduction by sodium of dicyclopentadienyltitanium(iv) dichloride: [(77-Cp)2TiCl]2, [(77-Cp)2-Ti]1-2, [(77-Cp)(C5H4)TiH]x, and (77-Cp)(C5H4)TiH2Ti- (C5H4)(77-Cp) ("stable titanocene"); the second of these reacts rapidly and rever...Hydrolysis; Sodium; Pressure1972
2 Miller, Joel StevenCollinear ferromagnetism and spin orientation in the molecule-based magnets M[N(CN)2]2 (M=Co,Ni)Zero-field unpolarized neutron powder diffraction has been used to study the low-T magnetic structure and T-dependent crystal structure of M[N(CN)2]2 (M=Co,Ni). Both compounds show collinear ferromagnetism with spin orientation along the c axis. The results provide the determination of a complete ma...Magnetic; Diffraction; Structure1999
3 Miller, Joel StevenNoncollinear antiferromagnetic structure of the molecule-based magnet Mn[N(CN)2]2The crystallographic and magnetic properties of the Mn[N(CN)2]2 compound have been investigated by dc magnetization, ac susceptibility, specific heat, and zero-field neutron diffraction on polycrystalline samples. The magnetic structure consists of two sublattices which are antiferromagnetically cou...Spin; Crystal; Magnetic2000
4 Poulter, Charles Dale; Jiang, YunfengBTS1 encodes a geranylgeranyl diphosphate synthase in Saccharomyces cerevisiaeProtein prenylation utilizes different types of isoprenoids groups, namely farnesyl and geranylgeranyl, to modify proteins. These lipophilic moieties attach to carboxyl-terminal cysteine residues to promote the association of soluble proteins to membranes. Most prenylated proteins are geranylgeranyl...Amino Acid Sequence; Cloning, Molecular; Gene Expression1995-09-15
5 Armentrout, Peter B.Reaction of Cr+, Mn+, Fe+, Co+, and Ni+ with O2 and N2O. Examination of the translational energy dependence of the cross sections of endothermic reactionsReactions of Cr+, Mn+, Fe+, Co+, and Ni+ with 02 and N20 to yield metal oxide ions are examined using an ion beam apparatus. Reaction cross sections a as a function of ion translational energy E are reported. With one exception, Fe+ + N20, the cross sections exhibit an energy threshold E0.Metal oxides; Endothermic reactions; Translational energy; Bond energy; Threshold energy1982
6 Armentrout, Peter B.Electron impact ionization cross section of metastable N2(A Σu+)Extensive studies of electron impact cross sections have been carried out both experimentally and theoretically for a number of ground state atoms and molecules.1 In general, as the electron energy is increased, such cross sections rise from a threshold at the ionization potential to a peak at an e...Ion beam; Nitrogen1981
7 Morse, Michael DavidRotational analysis of the 30 1 band of the Ã6Σ+ ← X̃6Σ + system of CrCCHThe spectrum of chromium acetylide, CrCCH, has been investigated in the near-infrared region (10 500-14 500 cm−1) and an intense band system is observed. The 310 band of this system has been investigated at high resolution (0.025 cm−1) and this system is identified as the ˜A6 + ← ˜X6 + syste...2014-01-01
8 Morse, Michael DavidUltraviolet photoelectron spectroscopy of molybdenum and molybdenum monoxide anionsThe 351 nm photoelectron spectra of Mo-and MoO- have been measured. The electron affinity of atomic molybdenum is 0.748(2) eV and that of molybdenum monoxide is 1.290(6) eV. The term energies of several MoO electronic states not previously observed are obtained and compared with ab initio prediction...1995
9 Armentrout, Peter B.Collision-induced dissociation of Fen+ (n=2-10) with Xe: ionic and neutral iron binding energiesCross sections for collision-induced dissociation (CID) of Fen+ with Xe, 2≤n≤10, are presented. Experiments were performed on a newly constructed guided ion beam mass spectrometer, the design and capabilities of which are described in detail. The single mechanism for dissociation of iron cluster...1989
