Further understanding of the Ru-centered [2+2] cycloreversion/cycloaddition involved into the interconversion of ruthenacyclobutane using the Grubbs catalysts from a reaction force analysis
(NLM (Medline), 2019)
The chemical reactivity of the first- and second-generation Grubbs catalysts has always been a significant issue in olefin metathesis. In the present work, we study the [2+2] cycloreversion/cycloaddition and the alkylidene ...
Vibrational study of N-phenyl-substituted hydroxynaphthylaldiminate copper(II) complexes
(1993)
The infrared spectra of seven bis(N-phenyl-substituted hydroxynaphthylaldiminate) complexes of Cu(II) were scanned from 4000 to 100 cm-1. Particular emphasis is given to the low-energy region. The assignment of the chelate ...
Normal Coordinate Analysis And Mean Amplitudes For C3-X4, 3 4 (X = Cl, I) Compounds
(1981)
Normal coordinate analysis of C3Cl4and C3I4has been carried out on the basis of general valen ce force field, using Wilson's FG matrix method. Approximate vibrational frequencies are calculated from very simple force field ...
Normal coordinates analysis of the hexamminochromium (III) ion. a simplified m(NX)6 model
(1983)
A normal coordinates analysis for the hexamminochro mium (III) ion, in octahedral symmetry has been underta ken. A simplified M(NX) model has been adopted, since many of the gerade vibrational frequencies are still un ...
Spectra and structure of polyamine-copper(II) complexes. Infrared spectrum and normal coordinate calculations of mono(diethylenetriamine) copper(II) nitrate
(1993)
The infrared spectrum of mono(diethylenetriamine)copper(II) nitrate has been obtained in the frequency range 4000-80 cm-1. Assignments of fundamental frequencies in the coordination site, as well as in the free and bonded ...
General valence force field and molecular dynamic parameters for cubic lanthanide hexachloro-elpasolite crystals
(1988)
A normal coordinate analysis has been carried out for the series Cs2NaLnCl6, where Ln represent a trivalent lan thanide cation such as Pr+ 3, Sm+3, Eu+3, Tb+ 3, Ho+3and Tm+3by using a general valence force field (GVFF). A ...
Normal coordinates analysis for the M(NH3)42+ complex ions in D4h and Td symmetries. Simplified molecular models
(1986)
A normal coordinates analysis for the M(NH3)42+ complex ions iN Td symmetry (M = Zn, Cd, Co) and in D4h symmetry (M = Cu, Pd, Pt) has been undertaken on the basis of a General Valence Force Field (GVFF), using simplified ...
Structural and vibrational theoretical analysis of the vanadium oxotrihalides, VOX3 (X=F, Cl, Br, I)
(Elsevier Science, 2004-03)
A structural and vibrational theoretical study of the vanadium oxotrihalides VOX3 (X ¼ F, Cl, Br, I) was performed employing ab initio (RHF) and Density Functional Theory methods. The existing vibrational data for the first ...
Friction coefficient and abrasive wear modes in ball-cratering tests conducted at constant normal force and constant pressure-Preliminary results
(ELSEVIER SCIENCE SA, 2009)
The micro-scale abrasive wear test by rotative ball has gained large acceptance in universities and research centers, being widely used in studies on the abrasive wear of materials. Two wear modes are usually observed in ...
