Notes:
Thirteen vibronic bands assigned to the two-photon 1 1Δu←A 1Πu transition, ν00=49 097±1 cm−1, have been observed by (2+2) resonance-enhanced multiphoton (REMPI) spectroscopy for laser wavelengths ranging from 370–480 nm. The measured term value Te=57 720±2 cm−1 of the previously unobserved 1 1Δu state is in good agreement with upper limits given by ab initio calculations. Additional spectroscopic constants measured for the 1 1Δu state are: D0=12 990 cm−1, ωe=1150±1 cm−1, ωexe=21.3±0.5 cm−1, Be=1.361±0.002 cm−1, αe=0.026±0.002 cm−1, and re=1.437±0.002 A(ring).
