Abstract: The TiO B$^{3}\Pi$- X$^{3}\Delta$ electronic transition ($\gamma^{\prime}$ system) is an important opacity source in the atmospheres of M dwarfs and hot Jupiter exoplanets. The 0–0, 1–0, and 2–1 bands of the B$^{3}\Pi$- X$^{3}\Delta$ band system have been analyzed using a TiO emission spectrum recorded at the McMath-Pierce Solar Telescope, operated by the National Solar Observatory at Kitt Peak, Arizona. Improved spectroscopic and equilibrium constants were determined. Line strengths were calculated from an \textit{ab initio} transition dipole moment function scaled using an experimental lifetime. A new line list for v$^{\prime}$ = 0-2 and v$^{\prime\prime}$= 0-4 of the B$^{3}\Pi$- X$^{3}\Delta$ band system is provided.
