Abstracts
The vibrational spectra of the protonated Schiff base of n-butylretinal (nSBR+) in dichloromethane
are studied. 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. (doi: 10.5562/cca1826)
