In this study, the carbyne complex, OsCl3(=CCH2CMe3)(PH3)2, structural, themochemical andelectronic properties were studied in solution and gas phases. For this investigation, the chosensolvents were five solvents (methanol, acetone, ethanol, DMSO, nitromethane) with variouspolarities. The influence of solvent polarity on the thermodynamic, structural, solvation energyparameters and frontier or...

Expressing spatial information with iconic gestures is abundant in human communication and requires to transform a referent representation into resembling gestural form. This task is challenging as the mapping is determined by the visuo-spatial features of the referent, the overall discourse context as well as concomitant speech, and its outcome varies considerably across different speakers. We...

English intonation can be difficult for L2 speakers to learn, particularly for those whose L1 intonation system works differently from English. This study investigates whether Hong Kong English (HKE) speakers whose L1 is Cantonese have knowledge of the appropriate English intonation patterns in specific contexts. Results from an intonation pattern selection tasks indicate that HKE speakers (n =...

This paper presents results of the spectral (absorption and emission) and photophysical study of 6-aminocoumarin (6AC) in various aprotic hydrogen-bond forming solvents. It was established that solvent polarity as well as hydrogen-bonding ability influence solute properties. The hydrogen-bonding interactions between S1-electronic excited solute and solvent molecules were found to facilitate the...

The different association behaviours of surfactants in water and other solvents have stimulated the interest to elucidate how the solvent properties influence aggregation, and many studies have been performed to gain information on the role of the solvent in the aggregation phenomenon of amphiphiles. These investigations have focused mainly on two essential aspects: namely the nature of the int...

The emission anisotropy (EA) of 4-Dimethyl-amino-4'nitrostilbene (DNS), 4-Amino-4'-nitrostilbene (ANS) and 2,5-Di(4-biphenylyl)oxazole (BBO) was observed to be decreasing with increasing dielectric constant e of the solvent. The effect is interpreted as an influence of the Onsager reaction field on the volume of the solvent shell, which in the excited state is smaller in solvents with larger e....
