Perturbations of the Distal Heme Pocket in Human Myoglobin Mutants Probed by Infrared Spectroscopy of Bound CO:Correlation with Ligand Binding Kinetics
Distal Heme Pocket Human Myoglobin Mutants Probed Infrared Spectroscopy Bound CO:Correlation Ligand Binding Kinetics
2016/5/23
The infrared spectra of CO bound to human myoglobin and myoglobin mutants at positions His-64, Val-68, Asp-60, and Lys-45 on the distal side have been measured between 100 and 300 K. Large differences...
MID-INFRARED SPECTROSCOPY OF CANDIDATE ACTIVE GALACTIC NUCLEI-DOMINATED SUBMILLIMETER GALAXIES
starburst submillimeter
2014/12/23
We report the detection of CO molecular line emission in the z = 4.5 millimeter-detected galaxy COSMOS J100054+023436 (hereafter J1000+0234) using the IRAM Plateau de Bure interferometer (PdBI) and NR...
MID-INFRARED SPECTROSCOPY OF CANDIDATE ACTIVE GALACTIC NUCLEI-DOMINATED SUBMILLIMETER GALAXIES
Spitzer spectroscopy evolutionary sequence
2014/12/20
Spitzer spectroscopy has revealed that 80% of submm galaxies (SMGs) are starburst (SB)-dominated in the mid-infrared. Here we focus on the remaining 20% that show signs of harboring powerful active ga...
Discriminant analysis of Olomouc curd cheese by Fourier transform near infrared spectroscopy
ripening Mahalanobis distance
2014/3/28
We used the discriminant analysis of curd cheese during storage by Fourier transform near infrared spectroscopy method (FT-NIRs). Olomouc curd cheese samples were stored at 5 and at 20°C during seven ...
Evaluation of ultraviolet, visible, and near infrared spectroscopy for the analysis of wine compounds

2012/4/5
High-resolution ro-vibrational spectroscopy of 15N216O in 1650-3450 cm-1 region is studied using highly enriched isotopologue sample. The positions of more than 7300 lines of 15N216O isotopologue were...
Infrared Spectroscopy of Comet 73P/Schwassmann-Wachmann 3 using the Spitzer Space Telescope
Infrared Spectroscopy Comet using Spitzer Space Telescope
2011/10/8
We have used the Spitzer Space Telescope Infrared Spectrograph (IRS) to observe the 5-37 micron thermal emission of comet 73P/Schwassmann-Wachmann 3 (SW3), components B and C. We obtained low spectral...
Using ground-based solar and lunar infrared spectroscopy to study the diurnal trend of carbon monoxide in the Mexico City boundary layer
ground-based solar lunar infrared spectroscopy diurnal trend carbon monoxide Mexico City boundary layer
2009/11/9
Carbon monoxide (CO) is an important pollutant in urban agglomerations. Quantifying the total burden of this pollutant in a megacity is challenging because not only its surface concentration but also ...
不同贮存温度蜂花粉的可见-近红外光谱鉴别（Application of Visible/Near Infrared Spectroscopy for Discrimination of Bee Pollen under Different Storage Temperature）
可见-近红外光谱技术 蜂花粉 贮存温度
2009/11/3
利用可见-近红外光谱技术结合最小二乘支持向量机（LS-SVM）对不同贮存温度下的蜂花粉进行鉴别。选择-20、4、15、25和40℃ 5个温度下分别贮存60d后的蜂花粉为研究对象。对原始光谱数据进行平滑和附加散射校正（MSC）的预处理后进行主成分分析，选择4～20个主成分作为输入变量进行LS-SVM建模。模型预测参数比较结果显示，当主成分数取20时模型的预测效果最好，预测相关系数r2p≥0.9919...
黄酒总糖含量的中红外光谱定量检测（Determination of Total Sugar Content in Chinese Rice Wine by Mid-infrared Spectroscopy）
总糖 黄酒 中红外光谱
2009/11/3
利用中红外光谱技术对黄酒中的总糖含量进行了快速检测。实验以3个厂家的共30个样品为研究对象，在1000～1500cm-1和2500～3000cm-1波段范围内建立了多元线性回归、主成分回归以及偏最小二乘回归模型，并比较了微分的光谱预处理方法对模型精度的影响。二阶微分光谱建立的偏最小二乘模型的精度最佳，交互验证的相关系数为0.984，RMSECV为0.765g/L, RPD为5.75，表明中红外...
