Espectroscopia Rotacional Abstract “Rotational spectroscopy” is the technique that measures the interaction of electromagnetic radiation with the rotational movements of a molecular system. The observation of transitions between rotational quantum levels requires that the system under study has rotational freedom – typically, molecules, ions or radicals in the gas phase. This limitation does not allow…

Espectroscopia. Abstract Spectroscopy is an experimental technique that is based on the use of light to study the composition, structure and properties of matter. The root of the word, from the Latin spectrum (image, appearance), refers to something like “observation of the hidden image”. Although it historically originates from the observation of visible light dispersed…

Conformational and vibrational reassessment of solid paracetamol. Abstract This work provides an answer to the urge for a more detailed and accurate knowledge of the vibrational spectrum of the widely used analgesic/antipyretic drug commonly known as paracetamol. A comprehensive spectroscopic analysis – including infrared, Raman, and inelastic neutron scattering (INS) – is combined with a…

Inelastic neutron scattering study of reline: shedding light on the hydrogen bonding network of deep eutectic solvents Abstract The solids choline chloride and urea, mixed in a 1 : 2 molar proportion, form the iconic deep eutectic solvent “Reline”. A combination of computational and vibrational spectroscopy tools, including inelastic neutron scattering (INS), have been used…

Studies on polymorph conversion in a new cyclodextrin inclusion compound. Abstract A novel beta-cyclodextrin (beta CD) inclusion compound was prepared using 4-phenylpyridine-N-oxide (PPNO) as the organic guest. The inclusion compound, beta CD.PPNO, was characterised both in solution and in the solid state using numerous techniques. H-1 NMR in aqueous solution allowed the determination of a…
