Collisions of dihydrogen cations with tetrahydrofuran molecules have been studied. Luminescence spectra and the emission functions of the excited products at projectile energies ranging from 8 to 1000 eV have been measured using collision-induced emission spectroscopy. The recorded spectra are dominated by the atomic lines of the hydrogen Balmer series, whose intensities decrease more quickly than derived by the quantum-theoretical principle. The spectra also exhibit weak molecular bands of vibrationally and rotationally excited diatomic CH fragments created in the A2Δp and B2Σp- electronic states. The collisional processes are identified and compared with the latest results on cation-induced fragmentation of tetrahydrofuran.
