  Raman-scattering measurements are performed in K${_x}$phenanthrene with the
nominal value ${x}$ ranging from 0 to 6.0 at room temperature. Based on the
Raman spectra, two phases (${x}$ = 3.0 and 4.0) are observed among the
K${_x}$phenanthrene, and the immediate phase (${x}$ = 3.5) is produced. Only
the ${x}$ = 3.0 phase is found to exhibit the superconducting transition at 5
K. The C-C stretching mods are observed to broaden and become disorder in
K${_x}$phenanthrene (nominal value ${x}$ =2.0, 2.5, 6.0), indicating some
molecular disorder in the metal intercalation process. This disorder is
expected to influence the nonmetallic nature of these materials. The absence of
metallic characteristics in those nonsuperconducting phases is provided from
the calculated electronic structures based on the local density approximation.
