Journal ArticleDOI
FT-Raman and infrared spectra and vibrational assignments for 3-chloro-4-methoxybenzaldehyde, as supported by ab initio, hybrid density functional theory and normal coordinate calculations
TL;DR: Investigation of the relative orientation of the aldehydic oxygen and chlorine atom with respect to the methoxy group has shown that two forms, O-cis and O-trans exist, with O- trans form being more stable.
Journal ArticleDOI
Identification of mineral compositions in some renal calculi by FT Raman and IR spectral analysis.
J. Tonannavar,Gouri Deshpande,Jayashree Yenagi,Siddanagouda B. Patil,Nikhil A. Patil,B.G. Mulimani +5 more
TL;DR: An combined application of Raman and IR techniques has shown that, where the IR is ambiguous, the Raman analysis can differentiate COD from COM and PCHT from MAPH.
Journal ArticleDOI
The vibrational spectra, assignments and ab initio/DFT analysis for 3-chloro, 4-chloro and 5-chloro-2-methylphenyl isocyanates.
TL;DR: The investigation of the internal rotation of the isocyanate, NCO, by B3LYP/6-31G* level of theory has shown that the moiety maintains nearly the same orientation in all the three compounds as in phenyl isochenate.
Journal ArticleDOI
Effect of nitro groups on the photo physical properties of benzimidazolone: A solvatochromic study
TL;DR: It has been observed that the correlation of the solvatochromic Stokes shifts with the parameter (E(T)(N), is superior to that derived using bulk solvent polarity functions for all the benzimidazolones reported in the present study.
Journal ArticleDOI
Experimental, DFT dimeric modeling and AIM study of H-bond-mediated composite vibrational structure of Chelidonic acid.
TL;DR: The AIM analysis confirms the presence of the intra- and inter-molecular H-bondings in the monomer/dimer species, and the natural bond orbital (NBO) analysis of the natural charges and stabilization energy of the H- bondings for the dimer species further points to the stronger inter-than intra-molescularH-bonding.
