Nitrogen quadrupole coupling constants determination

The nitrogen quadrupole coupling (NQR) constants of (3) were determined and the dipole moment confirmed as / = 1.58 0.02D (78ZN(A)1518). The NQR spectra for three... [Pg.514]

The 14N quadrupole hyperfine structure was analyzed from the MW spectrum and the nitrogen nuclear quadrupole coupling constants (NQCC) for aniline-Hy are determined as follows xaa = 2.34, Xbb = 1-86 and Xcc = —4.20 MHz38. [Pg.87]

In the case of nitrogen, whose nucleus has a spin 7=1, the situation is more favourable, as the experiment allows the determination of both the nuclear quadrupole coupling constant and the asymmetry parameter, and it is possible to make conclusions about sp hybridization, if the molecular geometry is known. However, the meaning of nuclear NQI for p electrons is not known with as much accuracy as for chlorine, bromine or iodine, but the estimation... [Pg.496]
