The trifluoroacetic acid (TFA) is used for the protonation of the Schiff base of nbutylretinal (nSBR). Combining the two-dimensional correlation analysis of the experimental infrared spectra with anharmonic frequency calculations it is shown that two types of ionic aggregates between nSBR+ and the TFA counterion are formed. The study suggests that the interaction between nSBR+ and the TFA counterion may be responsible for the observed lost of photoselectivity in the trans-cis isomerization of the nSBR+ in solution. |
