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."}],"article_number":"7039","publication_status":"published","year":"2015","article_type":"original","quality_controlled":"1","oa":1,"day":"05","status":"public","citation":{"ista":"Kraus PM, Tolstikhin OI, Baykusheva DR, Rupenyan A, Schneider J, Bisgaard CZ, Morishita T, Jensen F, Madsen LB, Wörner HJ. 2015.
