WebStereospecifically deuterated (6R)-[6-2 H 1]shikimic acid was administered to A. acidocaldarius blocked mutant 2 and labeled the resultant (61) with deuterium at the pro-2S position; in contrast, deuterium from (6S)-[6-2 H 1]shikimic acid was not retained. 69 The 1,4-conjugate elimination of water from shikimic acid to (57) thus occurs in an ... WebMay 28, 2014 · Resonance HR spectra of β-carotene in benzene, deuterated benzene, cyclohexane, and deuterated cyclohexane have been measured precisely for a quantitative analysis of this effect. The assignments of the observed peaks are made by referring to the infrared, Raman, and HR spectra of neat solvents.

WebThe physical properties of polymers depend on a range of both structural and chemical parameters, and in particular, on molecular topology. Apparently simple changes such as joining chains at a point to form stars or simply joining the two ends to form a ring can profoundly alter molecular conformation and dynamics, and hence properties.
