Abstract
The $^{3}B_{3u}-1Ag (\pi)$ band system of s-tetrazine with its origin at $13608 cm^{-1}$ is known (1-3) to be dominated by a progression built on the 6a10 in-plane ring breathing vibrational mode. A high resolution room temperature vapor phase intracavity absorption spectrum of the $6a^{2}_{0}$ band of s-tetrazine was recorded using photoacoustic detection. The band origin is located at $15043.8 cm^{-1}$ and the band is violet degraded. The sharp and extensive rovibronic features of this band are subjected to rotational analyses, the results of which will be presented along with a few interesting dynamic properties of the spin sublevels of this triplet state.
