Field-stepwise-swept solid-state
127 I NMR experiments of 1,4-diiodobenzene, C6 H4 I2 , applied to a Zeeman-perturbed NQR region, have been presented. A series of QCPMG measurements is performed at T = 90 K with resonant frequencies of 271 MHz in the range of magnetic fields from 2.5 T to zero with the interval of 12 mT. The spectral simulation, in which a numerical calculation involves the diagonalization of the combined Zeeman-quadrupolar Hamiltonian, provides quadrupole coupling constant (CQ ) = 1863(5) MHz and the asymmetry parameter (ηQ ) = 0.04(2). The127 I NQR spectrum is observed at T = 90 K, which is consistent in the above experimental results., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 Elsevier Inc.
