Abstract
Recent laboratory measurements of isotopologue $^{58}$NiH by laser excitation around 17000$-$18000 cm$^{-1}$ in a magnetic field have allowed us to study several electronic systems of this molecule. Zeeman patterns were analysed using literature values for ground state Lande factors (1997) 4179}. Effective electronic Lande factors $g_{\emph{eff}}$ have been determined. They show strong variation with parity in the rotational levels in some $\Omega'$=3/2 states, giving evidence for extensive mixing between excited electronic states. \newline %\begin{table}[h] % \scriptsize \begin{center} \begin{tabular}{|c|c|c|c|c|} \multicolumn{5}{c}{Effective electronic Lande factors $g_{\emph{eff}}$} \\ \multicolumn{5}{c}{}\\ \hline &\multicolumn{2}{|c|}{$E(\Omega=3/2),v=1$} & \multicolumn{2}{|c|}{$I(\Omega=3/2),v=0$}\\ \hline $J$ & $e$ & $f$ & $e$ & $f$ \\ \hline 1.5 & 1.058 & 1.142 & 1.640 & 1.638 \\ 2.5 & 0.992 & 1.365 & 1.937 & 1.895 \\ 3.5 & 0.844 & 1.737 & 2.371 & 2.294 \\ 4.5 & 0.587 & 2.238 & 2.870 & 2.734 \\ 5.5 & 0.415 & 2.933 & 3.552 & 3.328 \\ 6.5 & 0.233 & 3.671 & 4.326 & 4.110 \\ \hline \end{tabular} \end{center} % aption{Effective electronic Lande factors $g_{eff}$} %\end{table}
