Journal ArticleDOI
Self-Association of Formamide in Carbon Tetrachloride Solutions: An Experimental and Quantum Chemistry Vibrational and Thermodynamic Study
TL;DR: In this article, the structural and spectroscopic properties of formamide dimers, open or cyclic, were calculated using DFT procedures, with the B3LYP functional and 6-31G(d,p) or 6- 31G(p) basis sets, allowing proper assignments for the mentioned bands.
Journal ArticleDOI
The force constants in the isoelectronic series CF 3 SO 2 X (X=F, OH, NH 2 , CH 3 ): a study based on DFT calculations and experimental data
TL;DR: In this article, the authors performed density functional theory calculations at the B3LYP/6-31G(d,p) level of theory on the members of the isoelectronic series CF 3 SO 2 X (X=F, OH, NH 2, CH 3 ), in order to obtain the optimized geometric parameters and conformations for the four molecules, as well as the normal modes of vibration and the associated force constants.
Journal ArticleDOI
The structure of the FeNO group in two metastable states (MS1 and MS2) of the nitroprusside anion in Na2[Fe(CN)5NO].2H2O. Infrared spectra and quantum chemistry calculations for the normal and the 15NO and N18O isotopic substituted substance.
TL;DR: Comparison of the spectral data obtained for the FeNO moiety of the isotopically normal as well as of the (15)NO and N(18)O substituted anion with the results of quantum chemical (DFT) calculations support the assignment of the bands which appear after successive irradiation to MS1, the linear Fe(eta(1)-ON) linkage isomer, and to MS2, the side-bound Fe(ETA(2)-NO) isomer.
Journal ArticleDOI
Infrared and Raman spectra of 5-amino-1,3,4-thiadiazole-2-sulfonamide (Hats). Experimental data and quantum chemistry calculations
TL;DR: In this paper, the infrared and Raman spectra in the range 4000-50 cm −1 were obtained for 5-amino-1,3,4-thiadiazole-2-sulfonamide.
Journal ArticleDOI
The infrared spectra of trifluoromethanesulphonic acid in different states of aggregation
TL;DR: The infrared spectra of CF3SO3H in the gaseous, liquid and solid states, as well as dispersed in a solid Ar matrix, were obtained and analyzed as mentioned in this paper.
