Abstract
The fluorescence spectra of neurosporene and spheroidene were recorded in order to determine their 2A(g)(-) levels: each fluorescence spectr um was deconvoluted into two series of 1B(u)(+) -->1A(g)(-) and 2A(g)( -) --> 1A(g)(-) vibronic transitions, and the energy of the 2A(g)(- )( upsilon = 0) state was determined to be 15300 cm(-1) in neurosporene a nd 14200 cm(-1) in spheroidene. No temperature dependence of these ene rgies was seen. (C) 1998 Elsevier Science B.V. All rights reserved.
