NAME: isobutyraldehyde, 2-methylpropanal
FORMULA: i-C3H7CHO,(CH3)2CHCHO
AUTHOR(YEAR): LucazeauSandorfy(1970)
T: 298K
λ: 122.5-189.2nm(max)
BIBLIOGRAPHY: G. Lucazeau and C. Sandorfy, "The far-ultraviolet spectra of some simple aldehydes", J. Mol. Spectrosc. 35, 214-231 (1970); DOI: 10.1016/0022-2852(70)90199-2
COMMENTS: Absorption measurements using a hydrogen discharge tube as the light source and a vacuum spectrophotometer under 0.02 nm resolution

Molar extinction coefficients vs. wavenumbers for the absorption maxima and other selected points as listed in Table II have been converted to absorption cross sections (conversion factor 3.8235×10-21) vs. wavelengths
