This gives gx,y,z = 3.33, 1.22, 0.56, and hyperfine coupling constants of Ax = 1280 MHz (Ay and Az unresolved; we have assumed 𝑔̿ and 𝐴 ̿ are collinear) to the I = 7/2 nuclear spin of Nd (natural abundance: 12.2% 143 Nd and 8.3% 145 Nd). Similarly, frozen solution spectra of 1-Ce and 1-Sm can be simulated with gx,y,z = 3.15, 1.88, 0.64 for 1-Ce (Figure ; note there are no isotopes of Ce with I  0), and gx = gy = 0.92 for 1-Sm (Figure ). The gz component of 1-Sm is not well resolved in cw spectra but is more clearly defined in pulsed spectra giving gz = 0.45 (Figure ; see below). CW spectra of the related [Nd(Cp′′)3] (Cp′′ = C5H3-(SiMe3)2-1,3) have been reported, and although the precise g-values differ the pattern is similar. .
