Structure and vibrational assignment of cobalt(III) formylacetylacetonate
B-diketonate complexes of various metals have been used in the preparation of supported catalysts and as precursors of heterogeneous catalysts [1,2]. In this paper, the structure and vibrational spectra of cobalt(III) ...
Theoretical Molecular Structures and Vibrational Analysis of Monohalogenated Thiophenols
Thiophenol (benzenethiol) ArSH as a derivative of phenol belongs to the sulfur-containing compounds whose importance in atmospheric, environmental, biological, and medical areas can hardly be overestimated.Moreover, the ...
Fourier Transform Infrared and Raman Spectra and Structure of Methyl 3-(Amino)-2-Botenoate. A Density Functional Theoretical Study
Molecular structure and vibrational frequencies of methyl 3-(amino)-2-butenoate were investigated using density functional theory (DFT) calculations. The geometrical parameters and vibrational frequencies obtained in the ...
Structure and vibrational spectra of methyl 3-(methylamino)-2-Butenoate. A density functional theoretical study
Molecular structure and vibrational frequencies of methyl 3-(methylamino)-2-butenoate were investigated using density functional theoretical (DFT) calculations. The geometrical parameters and vibrational frequencies were ...
Spectroscopic Studies of intramolecular H bond in the enol form of -diketones. I. Frequencies assignment “Spectrochim
Abstract--The i.r. and Raman spectra of the trans-enol form of some /3-diketones and their
deuterated analogues in a position are examined in the 4000-50cm -~ range and an approximate
assignment is given for ...
Very strong intramolecular hydrogen bonding of 1,2-dithenoylcyclopentadiene; DFT and spectroscopic studies
Structure and intramolecular hydrogen bond (IHB) of 1,2-dithenoylcyclopentadiene (DTCP) have been investigated with quantum mechanical calculations using density functional theory at B3LYP level using some Pople-style basis ...
Vibrational spectra of Ocimum basilicum L. seed gum
The vibrational spectra of some components of Ocimum basilicum L. seed gum were investigated. After extracting and purifying the fractions, the mid and far Fourier Transform infrared (FT-IR) spectra of them were recorded. ...
Nutritional value, fourier transform infrared spectroscopic molecular structures, mycotoxines and heavy metals concentration of un-ripe, ripe and sun-dried fruit from 'Sultana' grapevine for ruminants
Grapes and grape-derived products have worldwide importance due to its consumption by human, however,
they may also be used for ruminant feeding when their price or quality is low. The objectives of current
study ...
Normal coordinate analysis, hydrogen bonding, and conformation analysis of heptane-3,5-dione
Fourier transform Raman and infrared spectral measurements have been made for the heptane-3,5-
dione (HPD) and simultaneously compared with those of acetylacetone (AA) to give a clear understanding of substitution ...
