Hyperfine Structure Constants for Diatomic Molecules
The multiconfiguration valence-bond method (VB) is applied to diatomic molecules using the Hartree-Fock (HF) atomic basis set. The hyperfine constant, Fermi contact term, is computed as a function of the interatomic separation for the X2∏ ground state of 17OH and X1∑ ground state of 107AgH+ molecules. This study leads to a number of conclusions about the influence of correlation and polarizatio...
متن کاملHyperfine structure theory and gap 1 morasses
Using the Friedman-Koepke Hyperfine Structure Theory of [2], we provide a short construction of a gap 1 morass in the constructible universe. §
متن کاملHyperfine structure of the Sic radical
The millimeter-wave rotational spectrum of the free 2’?SiC radical in the X 311 ground state, produced in a low-pressure glow discharge through SiH, and CO, was detected with the same reactive-molecule spectrometer used earlier to detect Sic and Si13C. Eleven rotational transitions, all but two with resolved hyperfine structure, were measured between 195 GHz (J = 4+ 5) and 372 GHz (J = 8 --+ 9)...
متن کاملHyperfine Structure and Tunneling Motion in Ethylenediamine
The first investigation of the microwave spectrum of ethylenediamine (NH CH –CH NH ) showed that in the gas phase this molecule occurs in two conformers which both exhibit a large amplitude tunneling motion corresponding to an interchange of the roles of the amino groups. In conformer I, the tunneling splitting is about 172 MHz while it is only 2.7 MHz in conformer II. In the paper an analysis ...
متن کاملMuonium hyperfine structure and hadronic effects
A new result for the hadronic vacuum polarization correction to the muonium hyperfine splitting (HFS) is presented: ∆ν(had – vp) = (0.233 ± 0.003) kHz. Compared with previous calculations, the accuracy is improved by using the latest data on e+e− → hadrons. The status of the QED prediction for HFS is discussed.
