Theoretical study of the force field and vibrational assignments of thioacetamide and its deuterated analogues
(Pergamon-elsevier Science LtdOxfordInglaterra, 2000)
An approach to reduce vibration and avoid shimmy on landing gears based on an adapted eigenstructure assignment theory
(2020-01-01)
Landing gear shimmy is a self excited vibration phenomenon which must be avoided during aircraft design due to its potentially catastrophic behaviour. In a preliminary specification of structural properties of a landing ...
Vibrational circular dichroism for the assignment of absolute configuration of natural products in Brazil
(Springer, 2021-12-02)
The determination of the absolute configuration of chiral bioactive natural products is a crucial step in their structural characterization.
Several well-established techniques, such as X-ray crystallography, stereo-controlled ...
VIBRATIONAL-SPECTRA AND ASSIGNMENT FOR PYRAZINE-N-OXIDE
(Acad Brasileira De CienciasRio De JaneiroBrasil, 1981)
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 ...
Vibrational and rotational spectroscopy of (CD3OD)-C-13
(Kluwer Academic/plenum Publ, 1999-02-01)
We have used Fourier Transform spectral data on the C-O stretching mode of (CD3OD)-C-13 in order to perform a vibro-rotational analysis for this molecule. We have estimated a few molecular parameters of the ground and C-O ...
Structural study and vibrational assignments of anticonvulsant topiramate by using dft calculations and two harmonic force fields
(AMG Transcend Association, 2020-09)
B3LYP/6-311++G** calculations have been combined with the scaled quantum mechanical force field (SQMFF) methodology to study structural and vibrational properties of anticonvulsant topiramate (TPM) agent. The 123 vibration ...
Photo-induced generation of the riboflavin-tryptophan adduct and a vibrational interpretation of its structure
(1994)
A pure fraction of a riboflavin-tryptophan adduct was obtained for the first time from a mixture of products resulting from the anaerobic photoirradiation of riboflavin and tryptophan in solution. The procedure used to ...
