Muonium adds to allyl chloride, CH2=CHCH2Cl, to form two radicals: MuCH2CHCH2Cl (main product) and CH2CHMuCH2Cl (minor product). Both radicals were fully characterized bySR andLCR. In the main product, the LCR lines due to the35Cl and37Cl nuclei were observed. Also, the temperature dependence of various hyperfine coupling constants (hfc) indicates that both Mu and Cl eclipse the unpaired electronp
2-orbital in the minimum energy conformation. For the fragment-CH2Cl, the presence of Mu in the-position is found to affect significantly the hfc of Cl in the-position; an internal rotational barrier of 12 kJ mol–1 was estimated using a simpleV
2 torsional potential. 相似文献

In this paper, we develop an interior point algorithm for quadratically constrained entropy problems. The algorithm uses a variation of Newton's method to follow a central path trajectory in the interior of the feasible set. The primal-dual gap is made less than a given in at most
steps, wheren is the dimension of the problem andm is the number of quadratic inequality constraints. 相似文献

We show that a compact complex manifold is Moishezon if and only if it carries a strictly positive, integral (1, 1)-current.
We then study holomorphic line bundles carrying singular hermitian metrics with semi-positive curvature currents, and we give
some cases in which these line bundles are big. We use these cases to provide sufficient conditions for a compact complex
manifold to be Moishezon in terms of the existence of certain semi-positive, integral (1,1)-currents. We also show that the
intersection number of two closed semi-positive currents of complementary degrees on a compact complex manifold is positive
when the intersection of their singular supports is contained in a Stein domain.

The problem of calculation of Sturmian functions (positive energy Weinberg states) for nonlocal (exchange) interactions is considered. It is shown that the method of continued fractions proposed by Horáek and Sasakawa makes the calculation of Sturmian eigenfunctions and eigenvalues feasible even for complicated nonlocal interactions. As an example Sturmian functions and Sturmian eigenvalues for the low energy electron-hydrogen scattering in the static exchange approximation are calculated. In addition a very general proof of convergence of the method of continued fractions is presented.Dedicated to the memory of Professor Jozef Kvasnica. 相似文献
