Feshbach resonances corresponding to metastable vibrational states of the dipole-bound state (DBS) have been interrogated in real time for the first time. The state-specific autodetachment rates of the DBS of the phenoxide anion in the cryogenically cooled ion trap have been directly measured, giving tau similar to 33.5 ps for the lifetime of the most prominent 11'(1) mode (519 cm(-1)). Overall, the lifetime of the individual DBS state is strongly mode dependent to give tau similar to 5 ps for the 18'(1) mode (632 cm(-1)) and tau similar to 12 ps for the 11('2) mode (1036 cm(-1)). The qualitative trend of the experiment could be successfully explained by the Fermi's golden rule. Autodetachment of the 11'(1)18'(1) combination mode is found to be much accelerated (tau <= 1.4 ps) than expected, and its bifurcation dynamics into either the 11(1)18(0) or 11(0)18(1) state of the neutral core radical, according to the propensity rule of Delta v = -1, could be distinctly differentiated through the photoelectron images to provide the unprecedented deep insights into the interaction between electronic and nuclear dynamics of the DBS, challenging the most sophisticated theoretical calculations.
