IR and Raman reference spectra of 156 compounds are presented along with the annotation summarizing their detailed group frequency assignments. The examples include organic, polymeric, polysaccharide, and inorganic compounds. The paired IR and Raman spectra provide illustrated examples of the characteristic...

Figure 3 1H NMR spectra of (a) PDAS (Mn ¼ 4590 g mol À1, PDI ¼ 1.27) and (b) fac-Ir(ppy)3 end-functionalized PDAS (Mn ¼ 5800 g mol À1, PDI ¼ 1.24), measured as a 3.0 wt% solution in deuterated chloroform at 50 1C. 4-DAS units. The peaks approximately 0.9...
some more modern O-PTIR systems can also provide Raman data simultaneously with infrared spectra from the same location at the same resolution. In this arrangement, the visible beam is used as the “infrared” probe, and it is also used as the excitation wavelength to elicit and acquire...
The digest was analyzed using the data-dependent multitask capability of the instrument acquiring full scan mass spectra using a Fourier Transform (FT) orbitrap analyzer to determine peptide molecular weights and collision-induced dissociation (CID) MS/MS product ion spectra with an ion-trap analyzer...
(a) FTIR spectra of Paraloid™ B-44 before (b) subtraction spectrum obtained after weathering in Florida for 18 months and (c) subtraction spectrum obtained after weathering in a QUV chamber for 2250 h. Asterisks were used to identify the same peaks as those labeled in the before ...
All acquired spectra were manually inspected and strictly revised as necessary. To test for statistically significant differences in deuterium uptake, all peptides and their respective spectra were analysed using a two-stage t-test as described in 76. In brief, the positive standard error of the ...
spectra. We applied these rather loose settings purposely in order not to miss too many cell type specific metabolites essential to establish cellular metabolic identity. Compounds were annotated by matching the obtained spectra with library spectra of Nist1449, FiehnLib50and golmDB51, where a match...
An example of a 2D IR spectrum for Ile33 is shown in Figure 3A (spectra of all labeled peptides are presented in Figure S3). The isotope label appears near 1590 cm-1 and is highlighted with a gray arrow in the magnitude spectra. We found in our previous work on the CD3ζ ...
The metalation of TFPP with Ir(III), in comparison with Pd(II), caused a bathochromic shift of approximately 7 nm in the absorption and emission spectra. Both transducers showed good phosphorescence at ambient temperature (23 ∘∘C); when IrTFPP-CO-Cl was embedded into PS, it presented...
