Abstract: | The vibration-rotation spectrum of the ν6 fundamental of methyl iodide has been recorded in the 824 to 862 cm?1 region by using a tunable semiconductor diode laser spectrometer. The rotational analysis performed for six Q branches pQ(J,3), pQ(J,4), pQ(J,5), pQ(J,6), pQ(J,7), and qQ(J,8) led to accurate values for several molecular constants. The nuclear quadrupole splitting arising from the spin of iodine has been observed very clearly in the low J transitions and for various K values. |
