Absolute intensities of about 120 lines of the (C2H2)-C-12 molecule are reported for the nu(4)-nu(5) band between 65 and 192 cm(-1), with an average accuracy of 5%. Vibrational transition dipole moment squared values and empirical Herman-Wallis coefficients are obtained allowing modelling the rotational dependence of the transition dipole moment squared. Special care is taken to accurately determine an apparatus function for the Bruker IFS 125-HR coupled to the synchrotron SOLEIL far infrared AILES beamline in order to minimize its effects on the line parameter retrieval.
