In this paper, the molecular dynamics of a series ester derivatives ibuprofen (IBU), in which hydrogen atom from hydroxyl group was substituted by methyl, isopropyl, hexyl, and benzyl moieties, has been investigated using Broadband dielectric (BD), Nuclear magnetic resonance (NMR), Raman spectroscopies. We found that except for IBU (Ben-IBU), an additional process (slow mode, SM) appears spectra all examined compounds. It is worth noting relaxation observed first time non-modified (a Debye...
In this paper, 1,6-anhydro-β-D-glucopyranose (anhGLU), 1,6-anhydro-β-D-mannopyranose (anhMAN), and 1,6-anhydro-β-D-galactopyranose (anhGAL), three new materials that form the Orientationally Disordered Crystal (ODIC) phase, have been thoroughly investigated using various experimental techniques. All measurements clearly indicated these compounds possess a series of very interesting physical properties are considerably different than those reported for ordinary plastic crystals. X-Ray...
The X-ray structure, theoretical calculation, Hirshfeld surfaces analysis, IR and Raman spectra of fluoranthene acenaphthene were reported. Acenaphthene crystallizes in the orthorhombic crystal system space group P21ma, with parameters a = 7.2053 (9) ?, b 13.9800 (15) c 8.2638 (8) Z 4 V 832.41 (16) ?3.

This paper presents the investigation results of polarized IR spectra hydrogen bond in crystals 3- and 4-methylthioacetanilide. The were measured at 293 77 K by a transmission method, with use light. main spectral properties can be interpreted satisfactorily terms "strong-coupling" theory, on basis centrosymmetric dimer model. revealed that strongest vibrational exciton coupling involved closely spaced bonds, each belonging to different chain associated 4-methylthioacetanilide molecules. A...
Molecules of the title compounds, 3'-methylacetanilide [or N-(m-tolyl)acetamide], C(9)H(11)NO, (I), and N-benzylthioacetamide, C(9)H(11)NS, (II), are connected by a framework intermolecular N-H...O N-H...S hydrogen bonds, respectively, forming chains with graph-set description C(4), which run along b axis.

In southern Poland, the mining industry led to creation of diverse post-mining waste deposited in dumps. Therefore, it is essential study and monitor condition soils developing there. The soil samples have been collected from coal dump at Ziemowit Coal Mine Upper Silesia, Poland. aim research was determine extent contamination by polycyclic aromatic hydrocarbons (PAHs) their derivatives within profile on that not subjected thermal phenomena (self-heating). Soil were taken depths 0, 20, 40...
Abstract Intra- and intermolecular studies on the molten L-sorbose have been carried out at variable temperature conditions to determine crosover ( T c ). In addition, isothermal time-dependent FTIR Raman measurements were performed probe pace of mutarotation activation energy this reaction in studied saccharide, which varied from 53–62 kJ/mol up 177–192 below above , respectively. To explain change barrier for a complementary analysis using difference spectra collected around = 365 K...
Differential Scanning Calorimetry (DSC), X-ray diffraction (XRD), Fourier Transform Infrared (FTIR) and Broadband Dielectric (BD) spectroscopies were applied to investigate the thermal, structural, photochemical dynamical properties of a fulgide-type photochromic compound, Aberchrome 670 (Ab670). In original crystals, characterized by pale yellow color, molecules take E conformation. However, upon UV irradiation either crystalline or glassy it isomerizes closed (C) form, intense red tone....
The reaction of N-(p-tolyl)acetamide with phosphorus pentasulfide in toluene gives the title compound, C9H11NS. amide group forms N—H⋯S hydrogen bonds adjacent molecules, linking them into chains.
The title compound, C8H9NS, was obtained by the reaction of N-methylbenzamide with phosphorus pentasulfide in toluene. In crystal structure, molecules related translation along c axis are linked into linear chains weak intermolecular N—H⋯S hydrogen bonds [N⋯S = 3.338 (2) Å].
Molecules of N-benzylacetamide, C9H11NO, are interconnected by a framework weak intermolecular N—H⋯O hydrogen bonds. The molecules form infinite hydrogen-bonded chains, parallel to the direction.
