  The electronic structure of six low-lying electronic states of scandium
hydride, $X\,{}^{1}\Sigma^+$, $a\,{}^{3}\Delta$, $b\,{}^{3}\Pi$,
$A\,{}^{1}\Delta$ $c\,{}^{3}\Sigma^+$, and $B\,{}^{1}\Pi$, is studied using
multi-reference configuration interaction as a function of bond length.
Diagonal and off-diagonal dipole moment, spin-orbit coupling and electronic
angular momentum curves are also computed. The results are benchmarked against
experimental measurements and calculations on atomic scandium. The resulting
curves are used to compute a line list of molecular ro-vibronic transitions for
$^{45}$ScH.
