Tunable UV Laser Photolysis of NF2: Quantum Yield for NF(a1 delta) Production.
Abstract
The ultraviolet photodissociation of difluoroamine (NF2) has been investigated from 240 to 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(a1 delta) were measured with 0.25/cm resolution. The NF(a1 delta) 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(X3 epsilon, an that the existence of a new higher lying NF2 electronic state is responsible for the NF(a 1 delta) production. Keywords: Photodissociation, Photolysis, Quantum yield, Nitrogen difluoride.
