The Raman peak table obtained by the DFT calculations was useful for assigning the Raman peaks measured by the experiments. The assignment of the Raman peaks of the C-H stretching mode of each fluoromethane hydrate coincided well with those estimated both experimentally and theoretically ill ...
摘要：分别测定了蓝晶石、红柱石和夕线石3种铝硅酸盐天然矿物晶体的Raman光谱，并利用Materials Studio3.0软件计算3种矿物的Raman振动频率，分析其简正振动模式，确定了三种矿物特征谱峰的归属，解析了铝对铝硅酸盐Raman光谱振动特征的影响。结果表明：随着四配位铝的增加(从蓝晶石、红柱石到夕线石)，800～1200cm–...

(Supplementary Table2). The fact that the match does not reach 100% can most likely be explained by instability of the Raman system (including laser and optical alignment) and signal fluctuation from the SERS NPs. For example, instability of the laser power, variation of the photon detection ...
Further, in the cytoplasm of MeV, infected cells presence of tyrosine (815 and 1629 cm−1) is specifically observed compared to the SARS-CoV-2-infected cells where tryptophan peaks (755, 1201, 1547, 1607 cm−1) are prominent (Table 1). Fig. 3: Principal component analysis (PCA)...
Boson peaksRaman spectraLow-viscous liquid formamidePolarised and depolarised low-frequency Raman spectra of liquid formamide have been analysed. The employed fitting procedure shows convincingly that the Boson peak contribution to the overall low-frequency Raman pattern is present even in this ordinary,...

One approach is to synchronize the data in software before applying multivariate analyses, and this approach is commonly used to time-sync chromatography peaks or pH, temperature, or dissolved oxygen. Time matching in-line and off-line data was automatically performed in the JITL studies by Tul...

Red: positive spectra with discernable CV-specific peaks (1); black: negative spectra without the targeted signals (0); blue: spectrum acquired in without CV (null control). The specific SERS band corresponding to CV (780 to 820 cm−1) is indicated by the orange stripes in panels a ...
