Methyl nitrite CH3ONO is an important species in atmospheric chemistry involved in photochemical oxidation of volatile organic compounds. The cis conformer (more stable by about 298 cm-1) has a high internal rotation potential barrier for the methyl group (731 cm-1) whereas for the trans conformer the barrier to internal rotation is extremely low (10 cm-1), leading to large internal rotation splittings. Only one high resolution infrared study was performed prior to this study. For the first time, high-resolution spectrum of CH3ONO was recorded in the far infrared region (30-500 cm-1) using the synchrotron SOLEIL far-infrared beamline (AILES) and a Fourier transform (FT) spectrometer. Some 987 lines were assigned for the cis isomer up to J=65 and combined with 66 previously recorded microwave lines. In addition, high-resolution spectrum of the ν9 band of the cis isomer around 627.9 cm-1 was also recorded using the FT spectrometer at LISA. New microwave data is currently recorded to improve the knowledge of both the cis and trans ground state parameters.
