News: Circular dichroism in the photoelectron angular distribution decays exponentially in ∼730 fs from a +9% forward amplitude during the first hundreds of femtoseconds to reach an asymptotic −2% backward amplitude after to have photoexcited at ~6 eV. This time-scale is drastically shorter than in fenchone, its isomer. Our analysis allows us to evaluate the impact of the anisotropy of excitation and reveal a breakdown of the Franck-Condon approximation.
