We study the “Catalogue of Isolated Pairs of Galaxies in the Northern Hemisphere” (CPG hereafter) by Karachentsev (1972), and a well matched comparison sample taken from the “Catalog of Isolated Galaxies” (Karachentseva 1973, CIG hereafter), in order to quantify the enhanced FIR emission properties of interacting galaxies (see Sulentic 1989 for details of the samples). The isolation criterion used in compiling the CPG and the CIG means that both the pairs and single galaxies have been Httle influenced by their environment for a long time (t ≳ 109 yrs: Stocke et al 1978).
