This is to our knowledge the first time, molecular resonance forms have basically been tracked by single-molecule conductance measurements. In future work we hope to be able to gain control over the conductance switching. One way of doing so may be to incorporate the D–A molecules in a ...
Continuous-wave EPR has been used to assign local secondary structure and to determine the membrane immersion depth of lipid-exposed residues in an α-Syn-lipid bilayer complex. The results indicated that α-Syn forms a curved alpha-helical structure which extends parallel to the curved membrane ...
These changes arise from differences in the electronic states of the two forms that can greatly alter the intensities of the numerous bands. The oxidized and neutral forms of the polymer both act as electron acceptors towards the gas phase species tested here (toluene, water, methanol, and ...
has been utilized for measuring solution pH [19], and an SPR temperature sensor integrated with toluene-filled hollow-core fibers has exhibited excellent biosensing performance [20]. Compared with traditional sensors, fiber optic sensors have the advantages of highly customizable and integrated ...
Secondly, the temperature dependence of these formyl shifts was measured in benzene and toluene. KLINCIC AND STOTIIISRS: K.M.K. STUDIES 2331 Toluene was used in this st~lclyto allow observatioils over a wider temperature range (-35" to 100' C). Thirdly, the generality of these trends ...
The above n.0.e.s strongly indicate that a rotation about the single bond, C(6)-C( 1l), separated two stable conformers which were the gauche forms about the gem-dimethyl groups and two 0 methylene groups of C-(1) and C-(5).Hence the more stable conformer was represented as (la...
Furthermore, a comparison of the substituent effects of the methyl and the thiomethyl groups, as in toluene and thioanisole, show relatively small differences (5b).Unfortu- nately the AA'XX' pattern of the 'H aromatic signals precludes correlations of 13C signals with ' H assignments. The ...
The origin of these shifts is considered. The \\{PMR\\} spectrum of o-nitrosotoluene is found to contain signals attributed to both monomeric and dimeric forms in carbon tetrachloride and d-chloroform solution.doi:10.1016/S0040-4020(01)82557-6R.J. Sundberg...
This unimer was successfully purified by liquid chromatography using basic alumina and toluene/acetone (gradient 0–2% of acetone). Product was isolated as a dark red solid with a yield of 6.5% (12 mg, 0.01 mmol). 1H NMR (300 MHz, CD2Cl2,δ/ppm): 8.80 (s, 4H, B3), 8.77–8.68 (...
The 14N coupling constant also increases with the polarity of the solvent used, while the aH value usually (but not always) decreases [32]. These observations can be partially rationalized by considering the equilibrium between the two limit mesomeric forms of a nitroxide, since the form ...
