摘要：
The microwave spectra of alpha-methyl-gamma-butyrolactone and 2-methylcyclopentanone have been reinvestigated using microwave Fourier transform spectroscopy. A-E splittings due to internal rotation of the methyl group have been observed in the ground and several vibrationally excited states for both molecules. From an internal-axis-method analysis of these splittings, values of the methyl group internal rotation barrier of 2.61 kcal mol-1 for alpha-methyl-gamma-butyrolactone and 2.41 kcal mol-1 for 2-methylcyclopentanone have been obtained.
