Syntheses based on norfluorocurarine. 5. NMR spectra of monomeric norfluorocurarine derivatives

NMR spectra of norfluorocurarine and seven of its derivatives were studied. The NMR spectral parameters were related to stereochemical features using molecular modeling by the semi-empirical AM1 approximation. The resulting steric characteristics of the molecules in solution agreed well with x-ray structure data. The only difference from the x-ray structure data was the ability of several substituents to rotate.     

Mixed value problem for a nonlinear differential equation of fourth order with small parameter on the parabolic operator

We study the solvability of mixed value problem for one type of nonlinear partial differential equation, consisting superposition of parabolic and hyperbolic operators. By the method of separation variables we obtain the countable system of nonlinear integral equation. We use the method of successive approximations. It will be proved the convergence of obtained series. We study the continuously dependence of solution from small parameter.
