More specifically, according to [i-5], the IR absorption band corresponding to this vibration lies in a very broad region of the spectrum (500-1100 cm-l). In the same region, in the spectra of most multiatomic molecules, absorption of other vibrations can be observed, for example, the ...

Higher energy regions of the IR spectrum (larger wavenumbers) will causestretchingof bonds where lower energy regions (smaller wavenumbers) will causebending and twisting. Thus, depending on the type of bond and the atoms involved in the bond, we can predict what they are based on which wavenum...

A photoluminescence (PL) spectrum of the diluted solution was obtained by radiating 370nm UV. The results are shown in FIG. 6. As shown in FIG. 6, the peak light intensity of the first compound (19) was observed at a wavelength of about 441 nm. Color purity corresponded to the CIE ...
Typically, when discussing IR spectroscopy MIR is the type of IR light that is used. The IR light in this range is useful because it coincides with an important property of chemical compounds: their vibrations. Positions of infrared radiation in the electromagnetic spectrum. NIR, M...
