Nuclear Quadrupole Hyperfine Structure of the Direct /-Type Transitions
The direct Itype transitions of H l 3 C , 4 N l 6 0 in the vibrational states ( i^ i ' s ) = (01) and (03) were measured in the frequency range from 18 to 40 GHz. These transitions show a nuclear quadrupole hyperfine structure caused by the l 4 N nucleus, which could partially be resolved at Doppler-limited resolution. The analogous transitions of the parent species. H l 2 C l 4 N 1 6 0 , were ...
متن کاملRovibrational levels of HD.
The dissociation energies of all rotation-vibrational states of the molecular HD in the ground electronic state are calculated to a high accuracy by including nonadiabatic, relativistic alpha(2), and quantum electrodynamic alpha(3) effects, with approximate treatment of small higher order alpha(4), and finite nuclear size corrections. The obtained result for the ground molecular state of 36 405...
متن کاملSUPPLEMENTAL MATERIAL FOR: Rovibrational levels of HD
The following tables collect components of the dissociation energy for all rovibrational levels of HD. The abreviations used within the table: BO – the Born-Oppenheimer component AD – the adiabatic correction NA – the nonadiabatic correction α – the relativistic correction of the order α α – the QED correction of the order α α – the QED correction of the order α Total – the total dissociation e...
متن کاملCommunication: General variational approach to nuclear-quadrupole coupling in rovibrational spectra of polyatomic molecules.
A general algorithm for computing the quadrupole-hyperfine effects in the rovibrational spectra of polyatomic molecules is presented for the case of ammonia (NH3). The method extends the general variational approach TROVE [J. Mol. Spectrosc. 245, 126-140 (2007)] by adding the extra term in the Hamiltonian that describes the nuclear quadrupole coupling, with no inherent limitation on the number ...
متن کاملNuclear quadrupole moment of 43 Ca and hyperfine structure studies of its singly charged ion
By combining our theoretical calculation and recently measured electric quadrupole hyperfine structure constant of the 3d 2 D 5/2 state in the singly ionized 43 Ca, we determine its nuclear quadrupole moment to one percent accuracy. The obtained result, −0.0444(6)b, is about ten percent improvement over the considered standard value. We have employed the relativistic coupled-cluster theory at s...
