Uridine absorption spectra

Fig. 6.—Ultraviolet Absorption Spectrum of Uridine at pH Values Indicated. (Adapted from Fox and Shugar.87)...

The ultraviolet absorption spectrum of the coenzyme corresponds to that of uridine. Bromine destroys the uracil moiety of the coenzyme and effects the destruction of biological activity. 

SAC-CI method was applied to calculate the electronic CD spectrum of uridine [43], Based on theoretical CD and absorption spectra, observed peaks in the experimental spectra were assigned. The rotational strength (R) in the length form [44] was calculated as imaginary part of the inner product of the electric transition dipole moment (ETDM) and magnetic transition dipole moment (MTDM).
