Considering the CDF of DMSO and water (cf. Fig.7), a similar good agreement of the overall pattern can be obtained between the results of the AIMD and FFMD simulations. The first peak (30 – 240 pm, 145 – 180∘) shows the hydrogen bond between DMSO and water. The second maximum a...
Proton nmr parameters are reported for DMSO-d6 solutions of two receptor-selective substance P analogues: Ac[Arg6, Pro9]SP6-11, which is selective for the NK-1 (SP-P) receptor and [pGlu6, N-MePhe8]SP6-11, which selectively activates the NK-3 (SP-N) receptor. Full peak assignments...
marginal peak could not be found in aqueous solution containing DMSO.In addition,with increasing amount of protein,T m (II)shifted toward lower temperature,and ΔH m (II)decreased along with the temperature gap between two transitions lengthened.The results were considered to be due to the ...

2D NMRCYTOCHROME C COMPLEXESLow-energy collisions of ionized acetone- d 6 , DMSO- d 6 and pyridine- d 5 with alkanethiolate self-assembled monolayer (SAM) surfaces prepared on gold were investigated. These experiments can be used to monitor routinely the condition of the surfaces and to ...
The new complexes have been characterized by IR, UV–Vis and H NMR spectroscopic methods. In addition, the structure of one of the complexes, [RuCl(DMSO)(tcah)]·HO (tcah = thiophene-2-carboxylic acid hydrazide), has been determined by single crystal X-ray diffraction. All the studies ...
