Pulsed slit jet diode laser spectra \n(instrumental bandwidth less than or equal to 25 MHz) of CF3I (neat and \nseeded in He) at rotational temperatures of about 7, 30, and 70 K have \nbeen obtained. The low J, K part of the observed transitions can be fitted \nby a model including the anharmonically coupled levels nu (1)(nu (0)\n=1076.0551 cm(-1)), 2 nu (0)(5)(nu (0)=1079.6732 cm(-1)) and nu (3)+3 nu \n(+/-3)(6)(nu (0)=1072.3884 cm(-1)), and the local Coriolis perturber nu (3)\n+3 nu (+1)(6)(nu (0)=1074.1845 cm(-1)). The level nu (3)+3 nu (+3)(6) was \nobserved and included for the first time, and an additional anharmonic \ncoupling between the levels nu (3)+3 nu (+3)(6) and nu (3)+3 nu (-3)(6) \nproved relevant. In order to analyze the higher J, K regions, \nperturbations arising from 2 nu (+/-2)(5) turned out to be important. In \ncertain regions of the spectra, effects due to nuclear quadrupole \ninteraction are clearly visible. We report new sets of parameters for a \nlow J, K model and for an extended model including the perturber 2 nu (+/-\n2)(5). The results are discussed in relation to infrared multiphoton \nexcitation of CF3I, infrared absorption in the atmospheric window and \nintramolecular vibrational redistribution." ; prodottidellaricerca:prodottoDi istituto:CDS054 .
