Recently DeMille et al proposed using 87SrF and other heavy diatomic molecules to measure nuclear spin-dependent parity violation (NSD-PV). In this scheme the N=0 (+-parity) levels of the X2 Sigma+ (v=0) state will be magnetically tuned into near degeneracy with the N=1(- parity) levels. The pairs of nearly degenerate levels are mixed by NSD-PV interactions. The process will be monitored using the optical A2 Pi-X2 Sigma+ transition. Here we report on the analysis of the (1,0) band for 88SrF and the (0,0) band for 87SrF of the A2 Pi-X2 Sigma+ system recorded at near natural linewidth limit. A combined fit of the optical spectra with the previously recorded rf-transitions and pure rotational transitions was performed.
