Figure 2: PES and dichroic parameter at 10.4 eV for the HOMO orbital of S-methyloxirane.

Figure 2

(a) Raw and (b) Abel-inverted difference (LCP–RCP) parent-ion mass filtered images, obtained with the velocity map imaging (VMI) spectrometer (see text for explanation). Note that the photon beam propagates from the bottom to the top of this image. (c) VMI-PES superimposed with the reference TPES of Fig. 1. (d) curve. The sticks correspond to the calculated vibrational spectrum. The error bars were obtained by assuming a Poisson distribution of the photoelectron image pixel intensities, and then propagating the Poisson s.d. through the image inversion transformation.
