摘要

摘要研究了充有二氧化硫和 H2O 与二氧化硫混合物的纳米孔的气凝胶的透射光谱。测量使用布鲁克 IFS 125 HR 傅立叶光谱仪在室温下进行，光谱范围为 4500-10 000 cm-1。研究发现，用二氧化硫以及 H2O 和二氧化硫分子的二元混合物填充样品的纳米孔会影响气凝胶的吸收带。这种变化是可逆的：当气体被抽出时，气凝胶样品的透射光谱就会恢复。

Transmission Spectrum of Nanoporous Aerogel Filled with SO2 and a Mixture of H2O and SO2 Vapors

The transmission spectra of aerogel with nanopores filled with SO₂ and a mixture of H₂O and SO₂ are studied. The measurements were carried out using a Bruker IFS 125 HR Fourier spectrometer in the spectral range 4500–10 000 cm⁻¹ at room temperature. It is found that the filling of nanopores of a sample with SO₂ and with a binary mixture of H₂O and SO₂ molecules affects the absorption bands of the aerogel. This change is reversible: when gases are pumped out, the transmission spectrum of the aerogel sample is restored.

期刊介绍： Atmospheric and Oceanic Optics is an international peer reviewed journal that presents experimental and theoretical articles relevant to a wide range of problems of atmospheric and oceanic optics, ecology, and climate. The journal coverage includes: scattering and transfer of optical waves, spectroscopy of atmospheric gases, turbulent and nonlinear optical phenomena, adaptive optics, remote (ground-based, airborne, and spaceborne) sensing of the atmosphere and the surface, methods for solving of inverse problems, new equipment for optical investigations, development of computer programs and databases for optical studies. Thematic issues are devoted to the studies of atmospheric ozone, adaptive, nonlinear, and coherent optics, regional climate and environmental monitoring, and other subjects.
