We demonstrate the double-peak spectral splitting in high-order harmonics generated in graphite plasma, which is mainly due to the propagation effects of high harmonics in the ionizing medium. The splitting of high harmonics can also be explained as a result of the double-peak structure in the spectral profile of the propagated driving pulse. The shift and intensity of these peaks, compared with unshifted harmonics, depend on different parameters of the experiment such as plasma density, the position of the focal plane, and laser intensity.
