    3. Results 3.1. Experimental Measurement of Infrared Absorption Spectra [13] As shown in Figure 2, CF 4 has two IR absorption bands; an intense band at 1270–1290 cm −1 and a much weaker band centered at 632 cm −1.CF 4 has a high degree of symmetry and consequently a relatively simple IR spectrum. The intense sharp
