Ultraviolet and infrared spectra of alkylphenanthrenes were analyzed. In ultraviolet spectra, the absorption maxima were classified into three groups and the first maximum of the group-II (phenanthrene : 291 mμ, log ε 4.17) was the most sensitive to the wave length shift by introduction of substituents. In infrared spectra the bands between 11∼15μ were analyzed as out-of-plane bending vibrations of the aromatic CH groups.
