Atmospheric CO2 concentrations, retrieved from spectral measurements made in the near infrared (NIR) by the SCIAMACHY instrument, using Full Spectral Initiation Weighting Function Modified Differentia...
This paper presents the first global distributions of CO vertical profiles retrieved from a thermal infrared FTS working in the nadir geometry. It is based on the exploitation of the high resolution a...
Total column amounts of CO, CH4, CO2 and N2O retrieved from SCIAMACHY nadir observations in its near-infrared channels have been compared to data from a ground-based quasi-global network of Fourier-tr...
The sensitivity of ground-based instruments measuring in the infrared with respect to tropospheric water vapour content is generally limited to the lower and middle troposphere. The large vertical gra...
Volatile Organic Compound (VOC) emissions from fires in tropical forest fuels were quantified using Proton-Transfer-Reaction Mass Spectrometry (PTRMS), Fourier Transform Infrared Spectroscopy (FTIR) a...
It is important to obtain the year-to-year trend of stratospheric minor species in the context of global changes. An important example is the trend in global ozone depletion. The purpose of this paper...
Emissions of air pollutants in and around urban areas lead to negative health impacts on the population. To estimate these impacts, it is important to know the sources and transport mechanisms of the ...
Within the framework of the Network for Detection of Atmospheric Composition Change (NDACC), regular ground-based Fourier transform infrared (FTIR) measurements of many species are performed at severa...
This paper describes the statistical analysis of annual trends in long term datasets of greenhouse gas measurements taken over ten or more years. The analysis technique employs a bootstrap resampling ...
Ground-based Fourier Transform Infra-Red (FTIR) measurements are an important component of the global atmospheric monitoring system. Their essential role in validating satellite measurements requires ...
Comparison of ground-based Brewer and FTIR total column O3 monitoring techniques     ground-based Brewer  FTIR  O3       font style='font-size:12px;'> 2008/11/20
We compare the currently most precise, ground-based total O3 measurement techniques: Brewer and FTIR. We give an overview of the similarities and the differences between the measurements and the retri...

我们已经合成了一系列具有生物活性的杂环取代苯并噁嗪酮类化合物, 为了构建一个苯并噁嗪酮类化合物的组合物库, 我们又探索出了一种固相合成7-氟-2H-1,4-苯并噁嗪-3(4H)-酮的方法, 并用FTIR技术成功地监测、优化了整个反应过程, 并根据得到的红外光谱图对反应动力学进行了探讨.
运用电化学循环伏安法(CV)和原位傅立叶变换红外(FTIR)反射光谱, 研究了不同pH值溶液中二甲醚(DME)在Pt电极上的解离吸附和氧化过程. 稳态CV结果给出, 在0.1 mol·L-1 H2SO4溶液中, 当电位处于0.05-0.35 V (vs RHE)区间, 约70%的Pt表面位被DME的解离吸附产物占据. DME电氧化反应的活性随pH值增加而下降, 在0.1 mol·L-1 NaOH溶...
DAC/FTIR和GC/FTIR联用技术鉴定爆炸残留物     GC/FTIR  DAC/FTIR       font style='font-size:12px;'> 2008/5/12
来自爆炸现场的爆炸残留物样品一般呈微粒状。利用配置高压金刚石池(AC)的傅里叶变换红外光谱仪(DAC/FTIR)可以检验小至1微克重的炸药微粒,测试样品在高压条件下,其红外吸收频率会向高波数位移。利用大口径熔融石英毛细管柱气相色谱与傅里叶变换红外光谱联用技术(GC/FTIR)可以分离、鉴定炸药混合物和现场提取的爆炸残留物。
