Photon emission arising during tetrahydrofuran (C4H8O, THF) fragmentation initiated by H3 + ion impact has been studied experimentally. Luminescence fragmentation spectra and the relative emission cross-sections of the excited fragments have been measured using collision-induced emission spectroscopy in the 20–1000 eV energy range. The main features in the spectra are the H Balmer series lines, whose intensities decrease with increasing principal quantum number n more quickly than predicted by quantum theory. Optical spectra also display weak emission of vibrationally and rotationally excited diatomic CH fragments. The possible mechanisms leading to the observed products are discussed.
