We have found that the visible absorption maximum (λ<SUB>max</SUB>) of retinal Schiff's base in fluoro alcohols is considerably red-shifted. The C=N stretching Raman line exhibits a frequency shift in deuterated fluoro alcohols, indicating that the Schiff's base is protonated. Frequencies of the in-phase C=C stretching Raman lines (ν<SUB>C=C</SUB>) changed linearly with λ<SUB>max</SUB>, and the ν<SUB>C=C</SUB> vs. λ<SUB>max</SUB> correlation coincides with that observed for retinoid proteins.
