• We review recent research on the acetylene S 1 state that illustrates how mechanistic rather than phenomenological information about intersystem crossing (ISC) may be obtained directly from frequency-domain spectra. The focus is on the dynamically rich “doorway-mediated” ISC domain that lies between isolated spectroscopic spin–orbit perturbations and statistical-limit interactions between one singlet “bright state” and a quasi-continuum of triplet “dark states”. New and improved experimental and data processing techniques permit the statistical-model curtain to be drawn back to reveal mechanistically explicit pathways via one or more identifiable, hence, manipulatable, doorway states, between a user-selected bright state and the undifferentiated bath of dark states.
