Comments: The electronic absorption spectrum of acetone is revisited to evaluate the role of hot bands due to low lying torsional modes in the assignment of vibronic transitions. The UV-VUV photoabsorption spectrum of acetone is recorded in the energy region 3.5–11.8 eV at a resolution of~4 meV at 4 eV and~10 meV at 10 eV using synchrotron radiation.
