Tunable UV laser photolysis of NF2: Quantum yield for NF(a 1Δ) production
Abstract
The UV photodissociation of NF2 has been investigated from 240-270 nm, using tunable UV radiation from a frequency upconverted YAG pumped dye laser system. The absorption cross section of NF2, and the photolysis quantum yield for the fragment NF(a1Δ) were measured with 0.25 cm-1 resolution. The NF(a1Δ) quantum yield decreases at longer wavelengths and is only 1% at 260 nm. This suggests that the first long wavelength band in NF2 leads primarily to ground state NF(X 3∑), and that the existence of a new higher lying NF2 electronic state is responsible for the NF(a1Δ) production.
