The bands of the vibrational structure of the n-π* transition in the high-resolution UV absorption spectrum of methacrolein vapor were assigned. The 0-0 transitions of the s- trans- and s- cis-isomers were evaluated: ν = 26484.3 cm, ν = 25288.8 cm. The fundamental vibration frequencies of both isomers were found not only for the ground state, but also for the excited one. The harmonic frequencies ω and anharmonicity coefficients x, as well as the frequencies of the 0-υ transitions of the torsional vibrations in both electronic states up to high values of the vibrational quantum number υ, were determined from the Deslandres tables constructed for the s- trans-isomer.
