大气气溶胶粒子在室内和室外环境中是丰富和普遍存在的。气溶胶中的有机酸物种由于其独特的界面性质而对环境和人类福祉的影响尚未得到充分研究。虽然人们普遍认为大气中气溶胶粒子的化学和物理演变与界面相关现象密切相关,但适用于现场调查这些主题的界面特定方法最近才出现。在这项研究中,我们阐述了最近发展的振动和频散射(VSFS)光谱作为一种界面特定的方法,在原位调查的亚微米悬浮在气体中的气溶胶颗粒的表面。我们证明了VSFS表征甲酸和乙酸的能力,单独和一起,在表面的水性气溶胶颗粒。我们评估分子有序的气体/气溶胶粒子界面通过检查偏振分辨VSFS光谱。最后,我们定量分析了简单的有机物的空气/液体界面,亚微米气溶胶表面和散装平面液体表面的界面亲和力。这些结果进一步支持使用VSFS作为探测小液滴和气溶胶表面的分析技术,并提供了深入了解平面和高度弯曲表面的化学之间的差异,对大气气溶胶化学具有潜在的意义。
Atmospheric aerosol particles are abundant and ubiquitous in both indoor and outdoor environments. Organic acid species in aerosols have an understudied effect on the environment and human well-being due to their unique interfacial properties. While it is widely accepted that the chemical and physical evolution of aerosol particles in the atmosphere is closely connected to interface-related phenomena, interface-specific methods suitable for investigating these topicsin situhave only recently become available. In this study, we elaborate on the recent development of vibrational sum frequency scattering (VSFS) spectroscopy as an interface-specific method for thein situinvestigation of the surfaces of submicron aerosol particles suspended in gas. We demonstrate the ability of VSFS to characterize formic and acetic acids, alone and together, at the surfaces of aqueous aerosol particles. We evaluate molecular ordering at the gas/aerosol particle interface by examining polarization-resolved VSFS spectra. Lastly, we quantitatively analyze the interfacial affinity of simple organics for the air/liquid interface, for submicron aerosol surfaces and bulk planar liquid surfaces. These results further support the use of VSFS as an analytical technique for probing the surfaces of small droplets and aerosols and provide insights into differences between the chemistry of planar and highly curved surfaces, with potential significance for atmospheric aerosol chemistry.
