The 2ν<SUB>3</SUB> band of methyl fluoride has been measured with a high-resolution infrared spectrometer. The following molecular constants are obtained: ν<SUB>0</SUB>=2081.382, <I>B</I>″=0.85172, <I>B</I>′=0.82955, (<I>A</I>″–<I>A</I>′)=0.01953, <I>D<SUB>J</SUB></I>″=1.95×10<SUP>−6</SUP>, <I>D<SUB>J</SUB></I>′=1.78×10<SUP>−6</SUP>, <I>D<SUB>JK</SUB></I>″=1.47×10<SUP>−5</SUP> (assumed), <I>D<SUB>JK</SUB></I>′=1.93×10<SUP>−5</SUP>, and (<I>D<SUB>K</SUB></I>″–<I>D<SUB>K</SUB></I>′)=5.9×10<SUP>−6</SUP>cm<SUP>−1</SUP>. In addition, the hot band (3ν←ν<SUB>3</SUB>) and the isotope <SUP>13</SUP>CH<SUB>3</SUB>F band have been observed and analyzed. The cubic force constant <I>k</I><SUB>333</SUB> was also obtained from the vibration-rotation constants.
