ResumoThe optical absorption of D -(–)-luciferin (LH 2 ) in ethanol is calculated by our previous LCAO-ASMO-SCF-CI method for π-electrons. It is found that the wavelengths of absorption of LH 2 observed in ethanol can be reproduced only when the screening of two-center Coulomb repulsion integrals is taken into account for all the pairs of atoms except bonded ones. It is also found that the observed absorption spectrum can be explained by the model of LH 2 interacting with two ethanol point-dipoles.
