Abstract: The $\tilde{A}^{2}$E$-\tilde{X}^{2}$A$_1$ transition of SrOCH$_3$ was first studied at high resolution by O'Brien et al. using a Broida oven. However lines with typically J$\leq$20 were not observed and congestion prevented them from resolving transitions from the $\Omega=1/2$ component of the upper state. We have studied the $\tilde{B}^{2}A_1-\tilde{X}^{2}A_1$ and the $\tilde{A}^{2}E-\tilde{X}^{2}A_1$ transitions of SrOCH$_3$ in a laser ablation molecular jet source, where jet cooling and low Doppler widths greatly simplified the spectra. An optical-optical double resonance technique facilitated definite assignments in a number of the transitions observed. Our analysis of the $\tilde{A}^{2}E-\tilde{X}^{2}A_1$ transition was straightforward, but a perturbation was observed in the $\tilde{B}^{2}A_1$ $K^{\prime}=1$ $F_2$ levels. A satisfactory fit was achieved for the $\tilde{B}^{2}A_1-\tilde{X}^{2}A_1$ transition when a separate $B$ parameter was used to fit the perturbed levels.
