Figure 2. Far-infrared absorption spectrum of N2+N2 at (a) 126, 149, and 179 K and (b) 228.3° and 300°K. Open circles, experimental data at (a) 124°K, and (b) 300°K of Buentempo et.al. (1975). Filled circles, squaries and triangles denote new results (Stone et al. 1984; Dagg et al. 1985). Lines, fitted spectrum, with the Ling and Rigby isotropic potential (see Appendix) and the dipole parameters given in Table 3. In (a), the scale is shifted by a factor of 2 at each temperature.
