TL;DR: Spectroscopic and structural study of a newly synthesized heteroligand complex of copper with creatinine and urea has been discussed and the complex is found to be rigid and stable in its monomeric form at very low concentrations.
Journal ArticleDOI
Solvent dependent frequency shift and Raman noncoincidence effect of SO stretching mode of Dimethyl sulfoxide in liquid binary mixtures
TL;DR: The non-coincidence effect (NCE) of DMSO was determined for all the solvents and compared with four theoretical models such as McHale's model, Mirone's modification of McHales' model, Logan's model and Onsager-Fröhlich dielectric continuum model respectively.
Journal ArticleDOI
Synthesis, characterisation, mesomorphic investigation and temperature-dependent Raman study of a novel calamitic liquid crystal: methyl 4-(4′-n-alkoxybenzylideneamino)benzoate
TL;DR: In this paper, a series of Schiff base calamitic liquid crystal; methyl 4-(4′-nalkoxybenzylideneamino)benzoate (MABAB), H2n+1C n OC6H4C(H)=NC6H 4COOCH3 (n = 6, 8, 10, 12, 14, 16) has been synthesized and characterised by elemental analyses, Fourier transform infrared spectroscopy (FT-IR), 1H and 13C Nuclear Magnetic Resonance (NMR) spectrograph
Journal ArticleDOI
Self-association and hydrogen bonding of propionaldehyde in binary mixtures with water and methanol investigated by concentration-dependent polarized Raman study and DFT calculations
TL;DR: In this article, the Raman spectra of neat propionaldehyde [CH3CH2CHO or propanal (Pr)] and its binary mixtures with hydrogen-donor solvents, water (W) and methanol (M), with different mole fractions of the reference system, varying from 0.1 to 0.9 at a regular interval of 0.
