In this paper we investigate the interaction between solitary-plain pulses (SP) of the quintic CGLE modified, which describes the soliton behaviour in the presence of spectral filtering, linear and nonlinear gains, and selffrequency shift (intrapulse Raman scattering). In particular, we look for a clear understanding of fundamental properties of the bound sates, especially as concerns their stability. We use the interaction plane (distancephase difference) to analyze the dynamics of the two soliton system. We have found stable BS's of plain pulses when the phase difference between them is π / 2 + ▵, and ▵ is a quantity that depends on a selffrequency shift coefficient.
