Abstract: We present the optothermal and optoacoustic spectra of CF_3Br in TEA CO_2 laser 00°1—02°0 R branch. Three absorption peaks has been observed at R(14) line (1074.6 cm~(-1)), R(18) line (1077.3cm~(-1)), and R(22) line (1079.9cm~(-1)) respectively. The peak at R(22) coincides with the position of P branch of CF_3Br linear IR spectrum, but two peaks at R(14) and R(18) can be interpreted as the hot bands.
We also studied the multiphoton dissociation of CF_3Br and carbon isotope seperation.
