The complete vibrational assignments for the alkaloid scopolamine as free base, quaternary scopolammonium cationic and hydrobromide species were reported for first time by using the internal coordinates, the scaled quantum mechanical force field (SQM
In this work, the structural, topological and vibrational properties of the monomer and three dimers of the 2-(4-nitrophenyl)-4H-3,1-benzoxazin-4-one (NPB) derivative were studied combining the experimental FTIR and FT-Raman spectra in the solid phas

With the specific aim of explaining the dipole moment (DM) of resorcinol in water, we investigated the molecular conformations and solute–solvent interactions of resorcinol in ethanol, methanol and water. In this work, experimental dielectric proce
