Ab initio and DFT methods were used to investigate the conformers of
Ethylnitrite. The potential energy surface for rotations around the C-O
and the O-N bonds was calculated. From the four geometrically possible
conformers only three were found to be stable in the calculations using
correlated methods. This is consistent with the microwave study Turner
(J.Chem.Soc.Faraday Trans. 2, (1979), 317) and with a presented matrix IR
spectrum which clearly shows three N=O stretching modes. A simulated ir
spectra using the results of the DFT calculations was in good agreement
with this matrix spectrum and allowed a tentative assignment of groups of
