The principal values of g -tensors and hyperfine tensors are determined; also the directions of their principal axes. The species in both crystals are tentatively assigned to NO2-3. In the crystals of Pb(NO3)2, the superhyperfine structure assigned to the interaction with three Pb nuclei is...
Resonance: The delocalization of pi-electrons in the planar conjugated system is known as resonance. The different structures obtained by the delocalization of pi-electrons are known as resonating structures. Answer and Explanation:1 We are told to draw the resonating structures forO3. ...
When two or more atoms come close together, the electrons in their atomic orbitals can interact and overlap, leading to the formation of molecular orbitals. Answer and Explanation: The carbonate ion (CO32−) has three resonance structures that can be ...

The platform structure shows a remarkably long 15N spin–lattice relaxation value (816 s, 14.1 T) for retaining its hyperpolarized spin state. The extended lifetime enables the detection of the hyperpolarized 15N signal of the platform for several tens of minutes and thus overcomes the intrinsic ...
