Vibrational frequency distribution correlation

The correlation of the vibrational frequency distributions of two modes can be determined from 2D-IR experiments and such effects are particularly evident in dual frequency experiments. For example, positive correlations between the amide-A and amide-I frequencies apparent from the spectra of acylalaninemethoxide (AcAlaOMe) in Figure 5, imply that when...

The vibrational satellite structure corresponding to the emission of the electronic state I is distinctly altered due to the perdeuteration. As expected (Sect. 4.2.10.1), all vibrational frequencies are red shifted, apart from the phonon satellite of 15 cm h However, by using the intensity distributions of the vibrational satellites, it is possible to correlate many of the vibrational modes of the perprotonated to those of the perdeuterated compound, as is carried out in Fig. 25.
