Abstract
Recently DeMille et al \underline {\textbf{100}} 023003, 2008.} proposed using $^{87}$SrF and other heavy diatomic molecules to measure nuclear spin-dependent parity violation (NSD-PV). In this scheme the $N$=0 (+-parity) levels of the $X^{2}$$\Sigma^+$ (v=0) state will be magnetically tuned into near degeneracy with the $N$=1(- parity) levels. The pairs of nearly degenerate levels are mixed by NSD-PV interactions. The process will be monitored using the optical $A^{2}$$\Pi$-$X^{2}$$\Sigma^+$ transition. Here we report on the analysis of the (1,0) band for $^{88}$SrF and the (0,0) band for $^{87}$SrF of the $A^{2}$$\Pi$-$X^{2}$$\Sigma^+$ system recorded at near natural linewidth limit. A combined fit of the optical spectra with the previously recorded rf-transitions \underline {\textbf{93}} 1990 93, 5533.} and pure rotational transitions \underline {\textbf{93}} 74, 1982.} was performed.
