“…In order to ensure that the data were free of any saturation effects [7,8], the cross-section was measured at an appropriate pressure in the range 0.03-1.3 mbar, with typical attenuations <40%. By limiting the absorbance to <40% we avoided both absorption flattening (when the transmitted intensity is very low), and poorly defined (and hence noisy) spectra when the transmitted intensity is high but close to the incident intensity.…”

Abstract. The high-resolution vacuum ultraviolet photoabsorption spectrum of isobutyl acetate, C 6 H 12 O 2 , is presented here and was measured over the energy range 4.3-10.8 eV (290-115 nm). Valence and Rydberg transitions with their associated vibronic series have been observed in the photoabsorption spectrum and are assigned in accordance with new ab initio calculations of the vertical excitation energies and oscillator strengths. The measured photoabsorption cross sections have been used to calculate the photolysis lifetime of this ester in the Earth's upper atmosphere (20-50 km). Calculations have also been carried out to determine the ionization energies and fine structure of the lowest ionic state of isobutyl acetate and are compared with a photoelectron spectrum (from 9.5 to 16.7 eV), recorded for the first time. Vibrational structure is observed in the first photoelectron band of this molecule.

“…The sample pressure is measured using a capacitance manometer (Baratron). In order to ensure that the data were free of any saturation effects [16,17], the cross section was measured at an appropriate pressure in the range 0.03−1.3 mbar, with typical attenuations <40%. In doing so, we avoided both absorption flattening (when the transmitted intensity is very low), and poorly defined (and hence noisy) spectra when the transmitted intensity is high but close to the incident intensity.…”

Electronic state spectroscopy by high-resolution vacuum ultraviolet photoabsorption, He(I) photoelectron spectroscopy and ab initio calculations of ethyl acetate

Abstract. The high-resolution vacuum ultraviolet photoabsorption spectrum of ethyl acetate, C4H8O2, is presented over the energy range 4.5−10.7 eV (275.5−116.0 nm). Valence and Rydberg transitions and their associated vibronic series observed in the photoabsorption spectrum, have been assigned in accordance with new ab initio calculations of the vertical excitation energies and oscillator strengths. Also, the photoabsorption cross sections have been used to calculate the photolysis lifetime of this ester in the upper stratosphere (20−50 km). Calculations have also been carried out to determine the ionisation energies and fine structure of the lowest ionic state of ethyl acetate and are compared with a newly recorded photoelectron spectrum (from 9.5 to 16.7 eV). Vibrational structure is observed in the first photoelectron band of this molecule for the first time.
