VLBI observations of molecular masers offer an unique opportunity to study the kinematics of the circumstellar gas in both the earliest and latest evolution phases of a star. The forthcoming Sardinia Radio Telescope (SRT) together with the other two Italian antennae of Medicina and Noto, will in the near future constitute a three-element VLBI array of sufficiently high sensitivity and angular resolution to allow one to map the strongest maser lines of CH<SUB>3</SUB>OH (at 6.7 GHz), H<SUB>2</SUB>O (at 22.2 GHz) and SiO (at 43 GHz). The Italian VLBI network (I-VLBI) can be competitive in the observation of molecular masers provided that time flexibility and frequency agility will be granted.ELETTRONICOenConference paperhttp://sait.oat.ts.astro.it/MSAIS/10/index.html2006MSAIS..10..102MFIS/05 - ASTRONOMIA E ASTROFISICA
