Journal ArticleDOI
FTIR, FT-Raman and DFT Calculations of 5-nitro-1,3-Benzodioxole
TL;DR: In this paper, the FTIR and FT-Raman spectrum of 5,benzo-1,3,benzodioxole were recorded and analyzed theoretically using the Gaussian03 set of quantum chemistry codes.
Journal ArticleDOI
Vibrational spectroscopic studies and computational study of methyl(2‐methyl‐4,6–dinitrophenylsulfanyl)ethanoate
TL;DR: In this article, the vibrational wavenumbers were computed using HF/6-31G* and B3LYP/6 -31G*) basis, which were used to assign vibrational bands obtained in infrared and Raman spectroscopies as well as in SERS of the studied molecule.
Journal ArticleDOI

TL;DR: In this paper, the Fourier transform infrared spectra of (E)-4-(benzylideneamino)-N-carbamimidoyl benzenesulfonamide were recorded and analyzed.
Journal ArticleDOI
Vibrational spectroscopic studies and computational calculations of 5-chloro-2-(3-chlorophenylcarbamoyl)phenylacetate
V.S. Madhavan,Y. Sheena Mary,Hema Tresa Varghese,C. Yohannan Panicker,Samuel Mathew,Christian Van Alsenoy,Jarmila Vinšová +6 more
TL;DR: The calculated first hyperpolarizability is comparable with the reported values of similar derivatives and is an attractive object for future studies of nonlinear optics.
Journal ArticleDOI
FT-IR, FT-Raman and quantum chemical calculations of (E)-N-carbamimidoyl-4-((3,4-dimethoxybenzylidene) amino) benzenesulfonamide.
Asha Chandran,Hema Tresa Varghese,C. Yohannan Panicker,T.K. Manojkumar,Christian Van Alsenoy,G. Rajendran +5 more
TL;DR: The results indicate that the B3LYP method is able to provide satisfactory results for predicting vibrational frequencies and structural parameters and is an attractive object for future studies of non-linear optics.
