The emission spectrum of AlO radicals was analyzed in 440-540 nm in the reaction of laser ablated Al beam and O 2. The carrier of spectrum was assigned to Δ ν =0, ±1, ±2 vibrational sequences of B 2Σ +-X 2Σ + transition of AlO radicals, the observed maximum vibrational quantum number was ν ′=6. The rotational and vibrational temperatures of B state were estimated at 3000 and 7500 K by spectrally simulating the rovibronic population distribution. There is a strong evidence that the production of excited Al( 2 S ) atoms is essential to the formation of excited AlO radicals.
The emission spectrum of AlO was analyzed in 440-540 nm in the reaction of laser ablated Al beam and O 2. The carrier of spectrum was assigned to Δν = 0, ± 1, ± 2 vibrational sequences of B 2Σ + -X 2Σ + transition of AlO radicals, the observed maximum vibrational quantum number was ν ’= 6. The rotational and vibrational temperatures of B state were estimated at 3000 and 7500 K by spectrally simulating the rovibronic population distribution. There is a strong evidence that the production of excited Al (2 S) atoms is essential to the formation of excited AlO radicals.
