Fission of the NH bond in pyrrole can be “controlled” by clustering the system to a single noble‐gas atom. Photofragmentation from the cluster takes place when the vertical excitation energy exceeds 5.27 eV (see picture). The measured intensity ratio between the slow and fast components of the H‐atom fragment from the photolysis of pyrrole at 230 nm changes from 0.35 to 1.33 when the carrier gas is He versus Xe.
