Mapping the ultrafast vibrational dynamics of all-trans and 13-Cis retinal isomerization in Anabaena Sensory Rhodopsin

The ground and excited state evolution of fingerprint vibrational modes of all-trans-and 13-cis-retinal are mapped by impulsive vibrational spectroscopy. All-trans-retinal shows slower frequency shift dynamics in the excited state in comparison to 13-cis-retinal
