Finally, the retained variables were employed as … Phosphorescence/ fluorescence (P/F) ratio for the indole-containing compounds. It was indicated that proposed WT-MUVE method could not only make the prediction more accurate, but also make the calibration model more parsimonious.

Deuteration was achieved as described in Materials and Methods. doi: 10.1371/journal.pone.0169430.

Temperature excursion infrared (TEIR) spectroscopy used to study hydrogen bonding between water and biomolecules. The spectra of glycerol in this range show much broader bands than the spectra of triacetin. Temperature was 290 to 12 K in 20 K increments. After the WT-MUVE process, variables for the calibration model were reduced from 7366 to 163. GLYCERIN

The spectrum from FTIR (fig 1.0), showed absorption frequency 3348.54cm-1 corresponding to an –OH and for glycerol in the liquid state [T. Uchino, T. Yoko, Science 273 (1996) 480.]. Furthermore, the reconstructed spectra represented the projection of the selected wavelet coefficients into the original domain, affording the chemical interpretation of the predicted results.

In some sense the spectrum of glycerol looks much more like the spectrum of water in the same range (see for example Ref. Emission band pass, 1 nm. Infrared (IR) and Raman spectroscopy was used to examine trehalose and sucrose films and glycerol/water solvent. The far-infrared result are compared to the low-frequency Raman spectra of the two liquids. 2012;875:375-91. doi: 10.1007/978-1-61779-806-1_20.
