The combination of single-shot signal referencing with the use of different metal foils to filter the attosecond pulse train enables us to extract delays from congested spectra. Remarkably large delays up to 160 as are observed in N2O, whereas the delays in H2O are all smaller than 50 as in the photon-energy range of 20-40 eV. These results are interpreted by developing a theory of molecular photoionization delays. The long delays measured in N2O are shown to reflect the population of molecular shape resonances that trap the photoelectron for a duration of up to ∼110 as. The unstructured continua of H2O result in much smaller delays at the same photon energies. Our experimental and theoretical methods make the study of molecular attosecond photoionization dynamics accessible."}],"publication_identifier":{"issn":["0031-9007"],"eissn":["1079-7114"]},"publisher":"American Physical Society","issue":"9","article_processing_charge":"No","keyword":["General Physics and Astronomy"],"scopus_import":"1","title":"Attosecond delays in molecular photoionization","date_updated":"2023-08-22T08:42:50Z","month":"08","citation":{"mla":"Huppert, Martin, et al. “Attosecond Delays in Molecular Photoionization.” <i>Physical Review Letters</i>, vol. 117, no. 9, 093001, American Physical Society, 2016, doi:<a href=\"https://doi.org/10.1103/physrevlett.117.093001\">10.1103/physrevlett.117.093001</a>.","ista":"Huppert M, Jordan I, Baykusheva DR, von Conta A, Wörner HJ. 2016.
