The phonon spectra of substitutional impurities in zincblende structure are calculated. The form law and characteristics for imparity induced local modes, gap modes and resonant modes are analyzed systematically. Besides the quasi-local mode above TA acoustic band, we also find a new low frequncy resonant mode just below TA acoustic band.
