P.S. Binil,Y. Sheena Mary,Hema Tresa Varghese,C. Yohannan Panicker,M.R. Anoop,T.K. Manojkumar +5 more
TL;DR: A computation of the first hyperpolarizability of the compound indicates that the compound may be a good candidate as a NLO material.
Journal ArticleDOI
FT-IR and FT-Raman study of Nasicon type phosphates, ASnFe(PO4)3 [A=Na2, Ca, Cd
C.J. Antony,A. Aatiq,C. Yohannan Panicker,M. Junaid Bushiri,Hema Tresa Varghese,T.K. Manojkumar +5 more
TL;DR: The spectral analysis shows that the symmetry of corner shared octahedral (SnO6) and the tetrahedral (PO4) are lowered from their free ion symmetry state and one of these tetrahedra is linearly distorted in all the title compounds.
Journal ArticleDOI
FT-IR, FT-Raman and computational study of 1H-2,2-dimethyl-3H-phenothiazin-4[10H]-one
R. Minitha,Y. Sheena Mary,Hema Tresa Varghese,Hema Tresa Varghese,C. Yohannan Panicker,Reena Ravindran,K. Raju,V. Manikantan Nair +7 more
TL;DR: In this article, the vibrational wavenumbers of 1H-2,2-dimethyl-3H-phenothiazin-4[10H]-one were computed using HF/6-31G(d) and B3LYP/6 -31G (d) basis.
Journal ArticleDOI
Potential dependent SERS profile of sulfanilic acid on silver electrode
TL;DR: In this article, the vibrational wavenumbers were computed by the ab initio method using HF/6-31G* basis and they were found to be in good agreement with the experimental values.
