-
(1992)The results of an investigation of the infrared spectra of mono(diethylenetriamine)copper(II) compounds are reported, with particular reference to the low-energy region. Most assignments are based on the available literature. ...
-
(2003)Fourier transform infrared spectroscopy (FTIR), reflection-absorption infrared spectroscopy (RAIRS) and surface-enhanced Raman spectroscopy (SERS) were applied to study the adsorption of the macrocycle sub-2,3-boronnapht ...
-
(1992)A comparison of some structural aspects of these complexes with Cp Re(CO)3 are also discussed. Additionally, the preparation and characterization of the trimethyl phosphite derivative is reported. A complete vibrationalassignment ...
-
(1992)Infrared spectra of solids Cp*Re(CO)2[PO(OMe)2]X, where Cp* = η5-C5Me5 and X = Cl, Br and I, were recorded. An assignment is offered in which the normal modes are described in terms of "local symmetry". This assignment is ...
-
(Elsevier, 2002)The FT-IR and Raman spectra in the solid state, the reflection-absorption IR spectra (RAIRS) and the surface enhanced IR (SEIR) and surface enhanced Raman spectra (SERS) of the Ni(II) (trans-7,14-dimethyl-5,12,-diphenyl- ...
-
(Texas State University, 2017)We consider vibrations modeled by the standard linear solid model of viscoelasticity with boundary dissipation. We establish the well-posedness and the exponential stability.
-
(Elsevier, 1997)A symmetry adapted formalism to evaluate the vibronic intensities induced by the ungerade vibrational modes in centrosymmetric coordination compounds of the rare earths is put forward and applied to several selected ...
-
(1991)The relative intensities of about 90 of the more prominent vibronic bands in the2Eg →4A2g luminescence spectrum of the MnF2-6 ion in Cs2SiF6 have been measured at 80 K. The reported intensities cover a range of more than ...
-
(1991)A method to estimate the contribution to the vibronic intensity in electronic transitions of inorganic complex ions due to second order terms in the Herzberg-Teller expansion of vibronic wavefunctions is developed and ...
-
(1990)The vibronic intensities of the vibronic origins due to the three odd-parity vibrational modes of the Г8(2T2g) Г8(4A2g) electronic transition of the ReBr2-6 ion are calculated using both crystal-field and ligand-polarization ...
-
(BLACKWELL, 2006-09)Individuals of social and partially social species typically reduce their vigilance activity when foraging in groups. As a result, per capita risk of predation decreases and individuals allocate more time to foraging and ...
-
(BioMed Central Ltd., 2014)© 2014 Díaz et al.; licensee BioMed Central Ltd.Background: Members of the Orthomyxoviridae family, which contains an important fish pathogen called the infectious salmon anemia virus (ISAV), have a genome consisting of ...
-
(Wiley-Blackwell, 2015)Most systematic studies of the avian visual system have focused on Neognathous species, leaving virtually unexplored the Palaeognathae, comprised of the flightless ratites and the South American tinamous. We investigated ...
-
(2007)Cellular glutathione levels may exceed vitamin C levels by 10-fold, generating the question about the real antioxidant role that low intracellular concentrations of vitamin C can play in the presence of a vast molar excess ...
-
(2012)Native to South America, Alstroemeria flowers are known for their colourful tepals, and Alstroemeria hybrids are an important cut flower. However, in common with many commercial cut flowers, virtually all the commercial ...
-
(NATL ACAD SCIENCES, 1997-05-13)Large conductance calcium- and voltage-sensitive K+ (MaxiK) channels share properties of voltage- and ligand-gated ion channels. In voltage-gated channels, membrane depolarization promotes the displacement of charged ...
-
(1975)When hemocyanin is added to a black lipid film, the conductance increases in discrete steps. For negative potentials the single step conductance is constant, but for positive potentials the step conductance appears to ...
-
(1994)The anodic electrochemical behavior of the five members of the 1,4‐dihydropyridine calcium antagonists family was studied. In all of the studied compounds (nifedipine, nitrendipine, nimodipine, nicardipine, and furaldipine), ...
-
(1993)This paper describes a method for the quantitative determination of aluminium in haemodialysis concentrates, based on the adsorption on a static mercury drop electrode of the Al-1,2 dihydroxyantraquinone-3-sulphonic acid ...
-
(AMER PHYSICAL SOC, 2011-04-29)We have found several families of vortex soliton solutions in two-dimensional discrete dissipative systems governed by the cubic-quintic complex Ginzburg-Landau equation. There are symmetric and asymmetric solutions, and ...
