dc.description.abstractThe absorption spectrum of methyl cyanide (CH3CN) has been measured in the near IR between 6000 and 8000 cm(-1) with a resolution of 0.12 cm(-1) using Fourier transform incoherent broadband cavity-enhanced absorption spectroscopy. The spectrum contains several weakly perturbed spectral regions: potential vibrational combination bands contributing to the spectrum are outlined. Line positions and cross-sections of CH3CN between 6814 and 7067 cm(-1) have been measured at high-resolution of 0.001 cm(-1) using diode laser based off-axis cavity-enhanced absorption spectroscopy. A total of 4630 new absorption lines of CH3CN are identified in this region. A value for the self-broadening coefficient has determined to be (3.3 +/- 0.2) X 10(-3) cm(-1) mbar(-1) for one isolated line at 7034.171 cm(-1). Several line series have been identified in these regions and an autocorrelation analysis performed with a view to aiding future assignments of the rotational-vibrational transitions.en
