A high resolution infrared spectrum of (CD3F)-C-13 has been recorded in the wavenumber region 820-1350 cm(-1) which covers four fundamentals v(2)(A(1)), v(3)(A(1)), v(5)(E); and v(6)(E); All strong and medium strong vibration-rotation lines have been assigned in terms of a model which treats simultaneously these strongly Coriolis coupled four fundamentals. Fifty-nine upper state parameters have been determined With t?eeieast squares method including 4390 infrared transitions as data. The standard deviation of the-fit obtained is 0.56X10(-3) cm(-1). Ground state rotational parameters have been determined using ground state combination differences. Due to strong vibration-rotation interactions a large number of normally forbidden-transitions have been observed which have allowed an accurate determination of the ground state axial rotational constant A(0) and the centrifugal distortion constant D-KO. The results of the analyzed infrared spectrum have made it possible to interpret many new laser emission lines from (CD3F)-C-13 gas optically pumped with a continuously tunable high pressure pulsed CO2 laser. Making use of the coincidence of the 10 mu m P and R branches of CO2 with the v(2), v(3), v(5), and v(6) bands, altogether 151 laser lines of (CD3F)-C-13 between 10 and 61 cm(-1) have been observed. These emission lines have been assigned as rotational transitions within the excited vibrational states and the ground vibrational state.
