The first hydrostatic core (FHSC) is a theoretical stage between the prestellar and protostellar phases of star formation. Eight candidate FHSC have been identified observationally but none have been definitively proven to be true first cores. The observational detection and confirmation of the FHSC is of prime importance in our understanding of the evolution of dense cores and star formation. We present high angular and velocity resolution observations of N2H+, SiO, CS, HCO+, HCN and NH2D for two FHSC candidates. In particular, N2H+ kinematic results are shown.
