Model of coupled spherical shell quantum wells is applied to C119 molecule. In a frame of the model the frequencies of the collective excitation series are calculated. The lowermost excitation, which could be detected by optical methods, is founded to have essentially dipolar character. Two types of the coupled oscillations exist with a different parity, which frequencies shifted up and down from C60 molecule plasmon frequency. For a dipole mode the two plasmon peaks with a gap about 3.5 eV have different dipole polarization. A transition to the usual coupled plasmons in two metal planes is fulfilled.
