Dielectric spectra of dimethyl sulfoxide (DMSO)/water mixtures, over the entire concentration range, have been measured using the transmission line method at frequencies from 45 MHz to 26 GHz and at temperatures of 298-318 K. The relaxation times of the mixtures show a maximum at an intermediate molar fraction of DMSO. The specific structure of mixtures in different concentration regions was de...

The pressure dependence of the decay of exciplex formed between acetophenone (AP) and N,N,N',N'-tetramethylbenzidine (TMB), and anthracene (A) and N,N-dimethylaniline (DMA) was studied in supercritical carbon dioxide by transient absorption and fluorescence techniques. Both the exciplexes showed similar trend in decay rate constant measured at various pressures of supercritical carbon dioxide. ...
