Responses to n-Stacking Interactions between Organic Structures 

In our work, computer-based methods were used to identify the individual contributions to overlapping vibrational bands for spectra (Fig. 7.12a) recorded in mixtures of dimethoxybenzene in cyclohexane. Fig. 7.12b shows that while the position of the higher wavenumber v y (CO) and v gy fCO) bands remains essentially constant, the new pair of v y (CO) and v y (CO) bands shift further to lower wavenumbers as the contribution of the n-stacking increases [50]. This is consistent with either additional n-stacking to form taller stacks [53], or shifts due to random solvent effects in the mixed cyclohexane/arene solvent environment The new pair of v y CO) and bands also broaden more as they shift
