(P = O) frequencies. They usually concentrated around 1241 cm−1on the FT-IR spectrum. These absorption bands are better observed in TS-Ph and SMS-Ph samples. Other main groups of observable absorption bands in the most IR spectra are related to the H2O related frequencies. The ...
of the similar absorption frequencies for those groups in different molecules. The actual frequency is affected by the environment, so the reference chart shows wide bands rather than specific frequencies. The identification of functional groups is a cornerstone of IR spectroscopy and organic chemist...

The digital difference spectrum technique in X-ray photoelectron spectroscopy has proved to be effective for the analysis of the functional groups introduced by surface oxidation treatment of carbon fibers. The major functional groups introduced to the carbon fiber surface by surface oxidation are hydroxy...
“Blattodea only” indicates unique presence to the blattodean lineage and in at least three genomes. “Specific” groups indicate specific presence or duplication in only one species. “Homology” indicates partial homology detected with E < 10−5but no orthology grouped. Remaining orthologs...
