| 英文摘要 | The difficulty in achieving high spectral resolution and accurate line shape in sum-frequency generation vibrational spectroscopy (sfg-vs) has restricted its use in applications requiring precise detection and quantitative analysis. recently, the development of high-resolution broadband sum-frequency generation vibrational spectroscopy (hr-bb-sfg-vs) with sub-wavenumber resolution generated by synchronizing two independent amplifier lasers have opened new opportunities for probing an intrinsic sfg response. here, we present a new flexible approach to achieve hr-bb-sfg-vs. in this system, two regeneration amplifiers shared the same oscillator laser as the seed, and a time-asymmetric visible pulse with a nearly lorentzian line shape filtered by an etalon was used to overlap with a femtosecond broadband infrared pulse. this lorentzian line shape of the visible pulse can greatly simplify the spectral fitting and analysis. we also demonstrated that the single-sided long visible pulse provided both high spectral resolution (1.4 cm(-1)) and effective suppression of the non-resonant background by detuning the time delay between visible and infrared pulses in sfg-vs measurements. with this new sfg setup, a pair of spectral splittings by 3.1 +/- 0.7 and 3 +/- 0.2 cm 1 for the symmetric and antisymmetric stretching of the ch3 group was resolved at the ch3cn/tio2(110) surface, which are tentatively attributed to two different orientational methyl groups. these technological advancements can help broaden the applications of hr-bb-sfg-vs and provide solid ground for a better understanding of complex molecular structures and dynamics at interfaces. published under license by aip publishing. |
