Transient absorption spectra in the visible (VIS) spectra region of: (A) all-trans-neurosporene; (B) central-cis-neurosporene; (C) all-trans-spheroidene; (D) central-cis-spheroidene; (E) terminal-cis-spheroidene; (F) all-trans-spirilloxanthin; and (G) central-cis-spirilloxanthin taken at various delay times after excitation. The spectra were recorded at 77 K in EPA for neurosporene and spheroidene and in 2-MTHF for spirilloxnthin.
