Extensive exploration into the catalytic potential of various PAHs has encompassed both theoretical investigations and experimental studies. In the present study, we focused on studying the reactivity of an imperfect aromatic molecule, indene (C9H8), and its hydrogenated counterpart, indane (C9H10), as potential catalysts for H2 formation within the interstellar medium. The reactions of these molecules with H atoms at 3.1 K were investigated experimentally using the para-H2 matrix isolation technique. Our experimental results demonstrate that both indene and indane are reactive toward H atoms. Indene can participate in H-atom-abstraction and H-atom-addition reactions, whereas indane primarily undergoes H-atom-abstraction reactions. The H-atom-abstraction reaction of indene results in the formation of the 1-indenyl radical (R1) (C9H7) and H2 molecule. Simultaneously, an H-atom-addition reaction forms the 1,2-dihydro-indene-3-yl radical (R2) (C9H9). Experiments also reveal that the H-atom-abstraction reaction of indane also produces the R2 radical. To the best of our knowledge, this study represents the first reporting of the infrared spectra of R1 and R2 radicals. The experimental results, combined with theoretical findings, suggest that indane and indene may play a role in the catalytic formation of interstellar H2. Furthermore, these results imply a quasi-equilibrium between the investigated molecules and the formed radicals via H-atom-addition and H-atom-abstraction reactions.}, year = {2024}, eissn = {1089-7690}, orcid-numbers = {Schneiker, Anita/0000-0002-8399-1529; Góbi, Sándor/0000-0002-7039-8099; Ragupathy, G./0000-0002-9435-5712; Tarczay, György/0000-0002-2345-1774} } @article{MTMT:34882889, title = {Three-photon absorption in lithium tantalate measured by the Z-scan technique}, url = {https://m2.mtmt.hu/api/publication/34882889}, author = {Benabdelghani, Imene and Bazsó, Gábor and Tóth, György and Rácz, Péter and Dombi, Péter and Hebling, János and Polónyi, Gyula}, doi = {10.1016/j.optmat.2024.115571}, journal-iso = {OPT MATER}, journal = {OPTICAL MATERIALS}, volume = {153}, unique-id = {34882889}, issn = {0925-3467}, year = {2024}, eissn = {1873-1252}, orcid-numbers = {Rácz, Péter/0000-0001-5099-1031; Dombi, Péter/0000-0002-0736-3512} } @article{MTMT:34772093, title = {Nonadiabatic Charge Transfer within Photoexcited Nickel Porphyrins}, url = {https://m2.mtmt.hu/api/publication/34772093}, author = {Naumova, M.A. and Paveliuc, G. and Biednov, M. and Kubicek, K. and Kalinko, A. and Meng, J. and Liang, M. and Rahaman, A. and Abdellah, M. and Checchia, S. and Alves, Lima F. and Zalden, P. and Gawelda, W. and Bressler, C. and Geng, H. and Lin, W. and Liu, Y. and Zhao, Q. and Pan, Q. and Akter, M. and Kong, Q. and Retegan, M. and Gosztola, D.J. and Pápai, Mátyás Imre and Khakhulin, D. and Daku, M.L. and Zheng, K. and Canton, S.E.}, doi = {10.1021/acs.jpclett.4c00375}, journal-iso = {J PHYS CHEM LETT}, journal = {JOURNAL OF PHYSICAL CHEMISTRY LETTERS}, volume = {15}, unique-id = {34772093}, issn = {1948-7185}, year = {2024}, pages = {3627-3638}, orcid-numbers = {Pápai, Mátyás Imre/0000-0002-4819-0611} } @article{MTMT:34596731, title = {Three-photon and four-photon absorption in lithium niobate measured by the Z-scan technique}, url = {https://m2.mtmt.hu/api/publication/34596731}, author = {Benabdelghani, Imene and Tóth, György and Krizsán, Gergő and Bazsó, Gábor and Szaller, Zsuzsanna and Mbithi, Nelson and Rácz, Péter and Dombi, Péter and Polónyi, Gyula and Hebling, János}, doi = {10.1364/OE.505995}, journal-iso = {OPT EXPRESS}, journal = {OPTICS EXPRESS}, volume = {32}, unique-id = {34596731}, issn = {1094-4087}, abstract = {Open-aperture Z-scan measurements have been carried out to investigate the three-photon (3 PA) and four-photon absorption (4 PA) coefficients at 800 nm and 1030 nm wavelengths, respectively in congruent and stoichiometric lithium niobate (cLN, sLN) with different concentrations of Mg doping. The laser pulse duration at the two wavelengths were 40 and 190 fs. The peak intensity inside the crystals varied between approximately 110 and 550 GW/cm 2 . The 3 PA and 4 PA coefficients were evaluated using a theoretical model and the results suggest that their minima are at or around the Mg doping level corresponding to the threshold for suppressing photo-refraction for both cLN and sLN. This result can be attributed to the contribution of crystal defects to the 3 PA and 4 PA processes. Furthermore, the 4 PA at 1030 nm exhibited greater nonlinear absorption than the 3 PA at 800 nm under the same intensity level. Possible reasons for this unexpected behavior are discussed. Overall, comparing the 3 PA and 4 PA values of these crystals will enable for selection of the optimum composition of LN crystal for efficient THz generation and for other nonlinear optical processes requiring high pump intensities.}, year = {2024}, pages = {7030-7043}, orcid-numbers = {Rácz, Péter/0000-0001-5099-1031; Dombi, Péter/0000-0002-0736-3512} }
