The $C2\Pi$ (v = 0) state of SrF has been investigated at high resolution using the technique of optical-optical double resonance spectroscopy. SrF was synthesized in a Broida-type oven by the reaction of Sr metal vapor with SF$\mathrm{<mrow\; data-mjx-texclass="ORD">6</mrow>}$. The band heads of the $A2\Pi -X2\Sigma +$ transition were first excited using a linear dye laser ($\sim$1cm$^{-1}$ bandwidth). A Ti:Sapphire ring laser was then utilized to record high-resolution laser excitation spectra of the $C2\Pi 1/2-A2\Pi 1/2$ and $C2$$\Pi 3/2-A2\Pi 3/2$ transitions. A rotational analysis of these transitions is in progress. In addition, an investigation of the $D2\Sigma +$ state is currently underway and preliminary observations will be presented.
