One-colour (∼220 nm) resonance-enhanced (S1 − S0) multi-photon dissociation of acetylene: probe of the C2 A1 Πu − X1 Σ+g band by frequency-modulation spectroscopy

In a recent paper, we demonstrated that one-colour (∼220 nm), resonance-enhanced (S1−S0), photodissociation of acetylene generates strong C2 Swan band (d3Πg−a3Πu) and C2 Deslandres-d'Azambuja band ...
