Full configuration interaction (FCI) calculations are carried out using the Slater determinant-based algorithm by Knowles and Handy. The linear combination of Slater determinants for singlet states that they mentioned is exploited and timing data is reported. A test calculation is performed for the Li2 molecule. The Schrodinger equation for the nuclear motion is olved to obtain spectroscopic constants for AlH. The constants obtained are in agreement with experiment within error of 4% on average.
