Abstract

A tunable, narrow-band ArF laser has been used for laser-induced fluorescence detection of NO in natural abundance in a flame experiment. P and R branches of the D2v′ = 0 ← X2Π3/2,1/2v″ = 1 transition were observed probing rotational states between J″ = 19.5 and J″ = 44.5. A single-shot detection limit of 1 part in 106 was found with a monochromator-based, dispersed-fluorescence detection system. In an experimental setup, determination of undispersed laser-induced fluorescence detection limits at or below the 1-part-in-109 range should be possible, because the narrow-band laser can be used to suppress all other sources of contaminating fluorescence even for detection of trace NO. The NO B2Π v′ = 7 ← X2Π v″ = 0 transition was also observed in a cell experiment but not in the flame and is reported here.
