The frequency of the vibration of the molecules is noted. This is theirstretching frequency. They behave like asimple harmonic oscillatorand their spectra are studied as Vibrational spectra or infrared spectra(IR). However, the levels of vibration are quantized and are given by'...

The intense band observed at 1628 cm−1 in the IR spectrum and the band at 1624 cm−1 in Raman have been assigned to the CO stretching mode. This decrease in stretching frequency is due to an increase in the p-conjugation between the ring and pyrone part. Also, the constraints ...
I am not sure exactly what you need to know, but I have found it helpful to bear in mind some simple concepts. For example the higher the bond order, the higher the frequency, all else held equal. So a carbon-carbon triple bond has a higher stretching frequency than a carbon-carbon ...
This is actually a traditional, most commonly used approach when the low - frequency shifts of OH stretching vibrations resulting from hydrogen bonding with adsorbed molecules, the heats of ammonia adsorption, the positions of ammponia thermodesorption peaks, or the adsorption of Hammett indicators ...
Additionally, the spectral bands at 548 cm−1 and 790 cm−1 correspond to Ir-O-Ir stretching and Ir-O out-of-plane vibration, respectively36,37. By analyzing the intensity trend of the Ir-O-Ir stretching peak (Supplementary Fig. 35b, c), we demonstrate that Ir undergoes ...
