The J=2←1 transitions of methyl iodide in the v<SUB>3</SUB>, v<SUB>6</SUB>, 2v<SUB>3</SUB>, v<SUB>2</SUB>, v<SUB>3</SUB>+v<SUB>6</SUB>, and v<SUB>5</SUB> vibrationally-excited states are observed. In v<SUB>3</SUB>+V<SUB>6</SUB>, the central component, ν<SUB>36</SUB><SUP>0</SUP>, of the J=2←1, K=1←1 transition is observed at 14.6 MHz, higher than the ν<SUB>36</SUB><SUP>+</SUP> of the <I>l</I>-type doubling. This is interpreted by the fact that the E state with K=−<I>l</I>=±1 is affected more strongly by the Fermi resonance through <I>k</I><SUB>356</SUB> than is the A state with K=<I>l</I>=±1. The Fermi resonance through <I>k</I><SUB>356</SUB> causes the Coriolis coupling between v<SUB>2</SUB> and v<SUB>5</SUB> through ζ<SUB>25</SUB><SUP>(y)</SUP> to be transferred to v<SUB>3</SUB>+v<SUB>6</SUB>. As a result, the <I>l</I>-type doubling constant, <I>q</I><SUB>6</SUB>, is determined to be −5.8 MHz. The Stark effect in the presence of the <I>l</I>-type doubling and nuclear quadrupole splitting is formulated and used in the analysis.
