Abstract: Recent Surface Electron Ejection by Laser-Excited Metastable (SEELEM) spectra have provided a clearer picture of the intersystem crossing of the $3\nu_{3}$ level of the $S_{1}$ surface of $C_{2}H_{2}$ to near-degenerate triplet states. The simultaneously recorded LIF and SEELEM spectra indicate that a single vibrational level of the $T_{3}$ surface couples the $3\nu_{3}$ level of the $S_{1}$ surface to a dense manifold of $T_{1}$ and $T_{2}$ states. This proposed coupling mechanism, Gateway Mediated Intersystem Crossing (GMISC), and other proposals will be discussed in light of the new data.
