execution. If you are working with a large screen monitor and you really want to see this macro as one gigantic picture, here's the way to do it. After stretching the width and height of the window until it completely filled my screen, I noted that the bottom line started at 462000 μ...
Terminology and Types of Fundamental Vibrations: Consider a methylene group-CH2 symmetrical stretching ((s CH2 ~ 2853 cm-1) (same symbol as used for frequency) asymmetrical stretching ((as CH2 ~ 2926 cm-1) (Note that asymmetric stretching occurs at slightly higher frequencies than symmetric ...

[41]. It should be noted that this assignment is in general agreement with the correlations between the O-H stretching frequency (as observed in the IR spectra) and the O-O distance around the hydrogen defects, as established by Nakamoto [93] and Libowitzky [94]. Due to the formation ...
Subsequent to the baseline correction, the FT-IR spectra were scaled to have equal intensity in the band at ≈ 1101 cm−1, which was assigned to the symmetric stretching vibrations of PO2−. The preprocessed spectral data were collected into an ASCII database (corresponding to 15 samples ...
