The optical properties of the intermetallic systems of the type MNiSn (M = Ti, Zr, Hf) have been studied for the first time in the frequency range 100 < ω < 4000 cm"1 at temperatures 10 < T< 300 K. An energy gap has been detected at the Fermi level. This gap becomes more pronounced as the temperature is lowered.
