Abstract
The electronic spectrum of the indene radical cation has been investigated through resonance-enhanced photodissociation of the weakly bound C 9H8+-He and C9H8 +-Arn (n = 1, 2) complexes in a tandem mass spectrometer. The D2 ← D0 band origin for indene+-He is observed at 17 379 ± 15 cm-1, while the D2 ← D0 and D4 ← D0 band origins for indene+-Ar appear at 17 353 ± 15 cm-1 and 28 254 ± 15 cm-1, respectively. The vibronic structure of the D 2 ← D0 band system is assigned by comparison with a simulated spectrum based on time-dependent density functional theory calculations, and is due mainly to progressions in ring deformation vibrational modes. Possible correspondences between the stronger visi..
