C 2 H 5 O plus its gauche and trans conformers are studied using synchrotron-based VUV photoionization mass spectrometry theoretical calculations, it is found that the conformer has favorable Franck–Condon factors in photoionization.

An efficient new procedure for calculating Franck-Condon factors, based on the direct solution of an appropriate set of simultaneous equations, is presented. Both Duschinsky rotations and anharmonicity are included, the latter by means of second-order perturbation theory. The critical truncation of basis set is accomplished by a build-up procedure that simultaneously removes negligible vibratio...
