The v6 vibration-rotational band of13CH3F has been measured in the range 1070-1260 cm-1 using a Fourier-transform spectrometer with unapodized resolution 0.0027 cm-1. The wavenumbers of 1262 vibration-rotational transitions to the v6=1 (E) vibrational state have been assigned and fitted by least squares with the standard deviation of the fit 1.31×10-4 cm-1. This made it possible to determine 19 spectroscopical parameters of the v6=1 state including parameters of the Δk=±2, Δl=∓2 and Δk=±4, Δl=∓2 interactions leading to the A1-A2 splittings of many rotational levels with kl=+1 and kl=-2.
