Resumen
We have measured the Raman spectrum of the dimethyl acetylene in the pressure range 0,1-62 kbar at room temperature. We have found three induced phase transitions at 0.1, 9 and 26 kbar. We have also found a massive polymerization reaction in this system which begins around 35 kbar. A force field treatment has been performed as a function of pressure, which allows analyzing the behaviour of the force constants with pressure for the dimethyl-acetylene.
