WebFTIR Spectroscopy, Fourier-transform infrared spectroscopy, is concerned with the vibration of molecules. Each functional group has its own discrete vibrational energy which can be used to identify a molecule through the combination of all of the functional groups. WebIn this paper, we proposed a simple approach to the prediction the key temperatures in diesel distillation process based on the raw near infrared (NIR) spectra of samples. After the NIR spectrum was decomposed by discrete wavelet transform to get the different NIR sub-signals, the selected sub-signals by genetic algorithm (GA) were superposed ...

"WebMar 1, 2016 · Singlet (3H) at ~2.4 ppm. Quartet (2H) at ~4.3 ppm. Doublet (2H) at ~7.2 ppm. Doublet (2H) at ~7.9 ppm. The two doublets lend to a disubstituted benzene. The IR absorption lends to a C=O. I came up with this structure: My thoughts were that the singlet owing to C H X 3 would be shifted to the left of the other C H X 3 due to the C=O.
