The title compound, [Ru(C(5)H(5))(C(3)H(5)N)(C(18)H(15)P)(2)]CF(3)SO(3), forms yellow crystals with a distinctly hemimorphic habit. It contains a half-sandwich complex of ruthenium with a three-legged piano-stool geometry, with Ru-P = 2.3585 (4) and 2.3312 (4) Å, and Ru-N = 2.0422 (15) Å as the legs. The CF(3)SO(3) (-) anion is anchored in the crystal lattice by C-H⋯O and C-H⋯F hydrogen bonds, ...

Gas phase reactions of mass-selected acylium ions [CH3–C ¢O (1), CH2¢CH–C ¢O (2), C6H5–C ¢O (3), and (CH3)2N–C ¢O (4)] with nitriles (CH3CN, C2H5CN, CH2¢CHCN, and C6H5CN) were investigated using pentaquadrupole multiple-stage mass spectrometry. In analogy with the solution behavior, the ions were found to react readily with benzonitrile by cyclization via double nitrile addition to form aromati...

  Nonspecific activity-related arm pain is characterized by an absence of objective physical findings and symptoms that do not correspond with objective pathophysiology. Arm pain without strict diagnosis is often related to activity, work-related activity in particular, and is often seen in patients with physically demanding work. Psychological factors such as catastrophic thinking, symptoms of...

introduction: in order to make a dimensional proportion between human and equipment or environment, anthropometric data bank is essential. anthropometry has an important role in industrial management and ergonomic design. this information is needed to be collected regularly in every society. the purpose of this study was to determine arm length to height ratio according to gender in adults, bet...

In the title compound, [Cu(C(3)H(5)N)(3)(C(12)H(18)N(6))](ClO(4))(2)·2H(2)O, the Cu(II) atom lies on a threefold rotation axis and is coordinated in a distorted N(6) octa-hedral environment by three tertiary amines from the tridentate chelating aza-macrocyclic ligand and three propionitrile mol-ecules. Inter-molecular non-classical C-H⋯N hydrogen bonding inter-links the [Cu(C(3)H(5)N)(3)(C(12)H...

Structural phase transitions have been observed using IR-VIS sum frequency generation (SFG) at the air/acetonitrile-water and the air/propionitrile-water interfaces but not at the air/butyronitrile-water interface. The phase transitions were detected by abrupt changes in the CN vibrational frequency and in the orientation of the CN chromophore as the interface nitrile density was varied. A mode...

Title of Document: STUDYING LIQUID DYNAMICS WITH OPTICAL KERR EFFECT SPECTROSCOPY Xiaoxiao He, Doctoral of Philosophy, 2015 Directed By: Professor, John T. Fourkas, Department of Chemistry and Biochemistry Time-resolved optical Kerr effect (OKE) spectroscopy is an established technique for studying the orientational dynamics of liquids. The reduced spectral density (RSD) obtained from transform...

The addition of acetonitrile, propionitrile, and acrylonitrile to tetramesityldigermene was investigated and compared to the addition of acetonitrile and acrylonitrile to germanium dimers on the Ge(100)-2×1 surface. In each case, a 1,2,3-azadigermetine was formed as the major product. As on the surface, the addition of nitriles to digermenes was found to be reversible, providing the first examp...

background: nonspecific symptoms are common in all areas of medicine. patients and caregivers can be frustrated when an illness cannot be reduced to a discrete pathophysiological process that corresponds with the symptoms. we therefore asked the following questions: 1) which demographic factors and psychological comorbidities are associated with change from an initial diagnosis of nonspecific a...
