Integrated band intensities of the 620 cm^(−1) absorption in (C_2H_2)_2 have been measured by FTIR spectroscopy at constant acetylene pressure between 198 and 273 K. These data, in conjunction with ab initio results for (C_2H_2)_2, have been used for the statistical evaluation of the equilibrium constant K_p(T) for acetylene cluster dimerization. Present results are used to clarify the role of molecular clusters in chemical systems at or near equilibrium, in particular in Titan's stratosphere.
