✦ Synopsis

Proton and infrared absorption spectra of seven peroxysterols of general structure 6&alkoxy-5,6&epidioxy-5~-5,6secocholestane-3/3,5-diol reveal low-field (6, 10.0-10.8) sharp one-proton singlets and associated sharp 3-330 cm-' absorption bands of the Sr-hydroxy group, intramolecularly hydrogen bonded to vicinal peroxide oxygen in a previously unrecognized correlation. The peroxysterols are also characterized by 13C NMR spectra. KEY WORDS Cholesterol Peroxysterol Hydroperoxide Epidioxide Hydrogen bond Low-field proton signals Infrared I3C NMR spectra Proton spectra.

Self-assembly has been widely used for the preparation of novel nanostructured materials. To both accelerate the dynamics of this processing route and develop new nanostructures, it is critical to understand the attendant interfacial interactions that occur in solution between the different precurso

## Abstract The NMR spectra of eight alkyl vinyl sulphides have been analyzed and the parameters compared with those obtained from an analogous series of oxygen derivatives. It is shown that a definite parallelism exists between chemical shifts and HH coupling. Difference in absolute values have b
