✦ Synopsis


RfT) and RfT were measured in their solid and solution states. The vibrational assignments of lumifiavin have been made on the basis of the observed isotope frequency shifts in the i.r. spectra. The differences between the skeletal vibrations of Lf and those of Rf are discussed. The modes of molecular association of Lf and Rf are also proposed based on the i.r. spectra of the carbonyl stretching region.

## Abstract Time‐dependent density functional theory has been applied to investigate the electronic absorption spectrum of oxidized and reduced lumiflavin and its derivative, 8‐NH~2~‐lumiflavin. The calculations allow the authors to explain the origin of the difference in spectral features between
