Using Fourier transform infrared(FT-IR) spectroscopy technique, the carbonyl stretching vibration bands of AOT in sodium bis(2-ethylhexyl)sulfosuccinate (AOT)/isooctane/water reverse (W/O) microemulsions system have been investigated by least square curve fitting. The results indicate that an asymmetric...
不同文章中描写FT-IR结果可能详略不一,下面列举一些比较常见的写法供大家参考。 A. 指派型(蓝色部分为写作模板) Figure 1b represents the characteristic peaks of PANI and PSS. The peak at 823 cm–1 results from (也可以换成 is caused by) the out-of-plane bending vibration of C–H on para-...
The IR signal is directly proportional to the amount of sample in the chromatographic peak that is flowing through the cell at any respective time. The flow cell must be able to withstand high pressure, have IR transparent windows and exhibit a volume considerably smaller than the peak volume....
The FT-IR and FT-Raman spectral measurements have been made for the 2,4-BDA. The complete vibrational analysis and first order hyperpolarizability, NBO analysis, HOMO and LUMO analysis, thermodynamic properties of the title compound was performed on the basis of DFT calculations at the B3LYP/6...

With the use of a Nicolet 60SX FT-IR, an MCT-A detector, 500 scans, and a 300-s sampling delay, five sets of triplicate runs, approximately one month apart, were made at each of 10 concentrations. Our results indicate the following conclusions: (1) quantification by peak height gives ...
peak near 11%. Retail void rates have stabilised around 6% and retail tenants are now generally benefitting from lower business rates bills from April, although many shoppers are still strapped for cash. Industrial void rates, although still below their long-term averages, have risen from 5% ...
Moreover, a clear endothermic peak at 34.5°C was obviously observed in the DSC thermogram in which the onset temperature was also Conclusions A newly developed thermal micro ATR/FT-IR spectroscopic system has been successfully and quantitatively applied to investigate the LCST and the molecular ...
Fig. 2. The representative FT-IR spectra of the control and different dose cyanide treated rat sperms in the ∼4000–500 cm−1 range. Table 1. Subchronic (90 days) cyanide induced changes peak position with their general band assignment based on the literature [55], [56], [57]]. ...
FT: Fourier-transformation, IR: infrared, NIR: near infrared, MIR: middle infrared, TPC: the total content of polyphenols, PLS: partial least squares regression, KPLS: kernel partial least squares regression, LS-SVM: least-squares-support vector machines method. When it comes to prediction using...
