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 ...

2D-IR Spectroscopy refers to a technique that enhances the amount of information obtained from a molecule's vibrational spectrum by spreading the response over a second frequency axis. It involves exciting each vibrational mode of the system and mapping out the correlation between the excited mode ...
