Singlet-triplet separations measured by [sup 31]P[l brace][sup 1]H[r brace] NMR: Applications to quadruply bonded dimolybdenum and d...
A series of quadruply bonded dimolybdenum and ditungsten compounds M[sub 2]X[sub 4](PP)[sub 2] (M = Mo, W; PP = bidentate phosphine ligands; X = Cl, Br,...
文献获取An Analytical Model for the Triaxial Collapse of Cosmological Perturbations
We present an analytical model for the nonspherical collapse of overdense regions out of a Gaussian random field of initial cosmological perturbations...
The Interaction of Nuclear Electric Quadrupole Moments with Molecular Rotation in Asymmetric Top Molecules. II. Approximate Methods ...
An expression is developed for the rotational dependence of for asymmetric top molecules. The expression is valid for all rotational energy levels, and ...
Polar [4 + 2 + ] Diels—Alder cycloaddition to nitrilium and immonium ions in the gas phase: Applications of multiple stage mass spe...
Multiple stage MS 2 and MS 3 mass spectrometric experiments, performed using a pentaquadrupole instrument, are employed to explore the gas-phase ion-mol...
Effects of Iron Starvation on the Physiology of the Cyanobacterium Agmenellum quadruplicatum
The effects of iron starvation on the growth and physiology of the unicellular cyanobacterium Agmenellum quadruplicatum were studied. Uptake of iron from the medium did not occur at a constant rate. The majority of the iron was remove...
The dynamics of ring rotation in ferrocene, nickelocene and ruthenocene by incoherent quadi-elastic neutron scattering
Incoherent quasi-elastic neutron scattering has been used to study the reorientational motions of the cyclopentadienyl rings in ferrocene, nickelocene and ruthenocene. The results for ferrocene show that the activation energy for ring...
Puzzling questions about excited superdeformed rotational bands of atomic nuclei are answered by the two-revolving-cluster model.
The two-revolving-cluster model provides explanations of several questions about excited superdeformed bands: restriction to the lanthanons and the Hg-T...
Spin1 Electrodynamics with an Electric Quadrupole Moment
The quantum theory of the electromagnetic interactions of a charged spin-1 particle is investigated, within the framework of canonical field theory. An ...
Accurate Mass Measurement by Electrospray Ionization Quadrupole Mass Spectrometry: Detection of Variants Differing by
Mass spectrometry has a basic limitation when human hemoglobin variants are analyzed, because it cannot resolve two globin chains that differ in mass by...
Magic-angle spinning nuclear magnetic resonance of half-integer quadrupole nuclei: effect of spin-locking efficiency on powder lines...
23 Na spin-lock magic-angle spinning (MAS) and cross-polarization (CP) MAS nuclear magnetic resonance (NMR) spectra have been traced for sodium-containi...
