Molecular structure of dimethyl sulfoxide intercalated kaolinites
Article Abstract:
Raman spectroscopy is used in studying the changes in the molecular structure of a low- and high-defect kaolinite intercalated with dimethyl sulfoxide (DMSO). The chlorite fractions are separated from kaolin minerals by using DMSO. However, the use of DMSO and deintercalation increases the stacking disorder in the kaolin. Spectroscopy results indicate there are two types of intercalated water for the low-defect kaolinite and three types of water for the high-defect kaolinite. It has also been observed that there are two types of DMSO molecules in the intercalate.

A strategy for characterizing the mixing state of immiscible aerosol components and the formation of multiphase aerosol particles through coagulation
Article Abstract:
The combination of optical tweezers and Raman spectroscopy is used to study the coagulation of two liquid aerosol droplets and also the formation and properties of multiphase aerosol. The experiment has allowed the detailed kinetic and thermodynamic measurements of phase partitioning in multiphase/multicomponent aerosol in order to understand the role of organic/inorganic/aqueous aerosol in the atmosphere and also of interparticle interactions and coagulation.

Using spectroscopic data on the imidazolium cation conformations to test a molecular force field for ionic liquids
Article Abstract:
A molecular force field for the computer simulation of ionic liquids is evaluated by confrontation against Raman spectroscopy data, published after the force field was formulated. The terms in the force field describing the conformational aspects of dialkylimidazolium cations, which were specifically developed for these compounds using high level ab initio calculations, are those affecting the distribution of conformers in simulated ionic liquids.
