Abstract

The infrared spectrum of methyl isocyanide, CH3NC, has been measured in the region $2120-2190 cm^{-1}$ at a resolution of $0.002 cm^{-1}$ using a Bomem $DA_{3}$ Fourier-transform spectrometer. The $\nu_{2}$ fundamental band and two combination band. $\nu_{2}+\nu_{8}-\nu_{8}$ and $\nu_{2}+2\nu_{8}-2\nu_{8}$, have been assigned. Molecular constants for the upper states of the three bands have been derived using the ground state constants determined by microwave $spectroscopy^{1.2}$ and fitting procedures and programs developed by $Plfva^{3}$.
