This book was released on 1990 with total page 29 pages. Available in PDF, EPUB and Kindle. Book excerpt: For the first time, the branching ratio for the H + NF2 has been measured using direct detection of the excited NF a(1) delta and the ground NF(X3 delta - ) states. NF a(1) delta was observed by its emission at 874 nm from both the 249 nm photolysis of NF2 and from the reaction of H atoms (produced from HBr photolysis at 193 nm) with NF2. While NF X3 delta - was easily detected by laser induced fluorescence on the NF b(1) delta - X3 delta - transition following 249 nm NF2 photolysis, it was no observed following the H + NF2 reaction. This result leads to a lower limit for the NF(a) branching ratio, NF(a)/NF sub tot> 0.90 + or - 0.03, in accord with previous results. The measured NF a(1) delta quantum yield from KrF photolysis of NF2, (Theta)NF(a)

Book excerpt: Laser induced fluoresence (LIF) spectra (laser excitation spectra) are conceptually among the most simple spectra to obtain. One need only confine a gaseous sample in a suitable container, direct a laser along one axis of the container, and monitor the sample's fluorescence at a right angle to the laser beam. As the laser wavelength is changed, the changes in fluorescence intensity map the absorption spectrum of the sample. (More precisely, only absorption to states which have a significant radiative decay component are monitored.) For ion spectroscopy, one could benefit in many ways by such an experiment. Most optical ion spectra have been observed by emission techniques, and, aside from the problems of spectral analysis, discharge emission methods often produce the spectra of many species, some of which may be unknown or uncertain. Implicit in the description of LIF given above is certainty as to the chemical identity of the carrier of the spectrum. This article describes a method by which the simplifying aspects of LIF can be extended to molecular ions (albeit with a considerable increase in experimental complexity over that necessary for stable neutral molecules).
