In particular, attosecond streaking, laser-induced electron diffraction and high-harmonic generation all make use of non-perturbative light–matter interactions. Remarkably, the effect of the strong laser field on the studied sample has often been neglected in previous studies. Here we use high-harmonic spectroscopy to measure laser-induced modifications of the electronic structure of molecules. We study high-harmonic spectra of spatially oriented CH3F and CH3Br as generic examples of polar polyatomic molecules. We accurately measure intensity ratios of even and odd-harmonic orders, and of the emission from aligned and unaligned molecules. We show that these robust observables reveal a substantial modification of the molecular electronic structure by the external laser field. Our insights offer new challenges and opportunities for a range of emerging strong-field attosecond spectroscopies."}],"oa":1,"external_id":{"pmid":["25940229"]},"_id":"14016","status":"public","volume":6,"publication_status":"published","quality_controlled":"1","article_processing_charge":"No","type":"journal_article","date_published":"2015-05-05T00:00:00Z","title":"Observation of laser-induced electronic structure in oriented polyatomic molecules","scopus_import":"1","date_created":"2023-08-10T06:38:01Z","article_number":"7039","citation":{"ama":"Kraus PM, Tolstikhin OI, Baykusheva DR, et al.
