Our team recently found that the S3 to S2 internal conversion of n-protonated azaindoles (n-AIH + ) was ultrafast, despite the absence of energetically accessible conical intersections. For 6-AIH + , surface hopping simulations predicted an S3 lifetime of 156  40 fs, even though the energy gaps at the hopping time had a distribution with a 0.47 eV mean value and 0.13 eV standard deviation. Similarly, for 7-AIH + , the predicted S3 lifetime was 278  36 fs with energy gaps at the hopping times having also a 0.47 eV mean value and 0.22 eV standard deviation.
