In this communication we propose a new Laser Induced Fluorescence (LIF) scheme that allows the simultaneous detection of OH and NO by a single laser set-up. OH is detected by the Second Harmonic (SH) of a dye laser tuned to the (0,0) band of the 3064 Å system, while its Third Harmonic (TH) is used to detect NO through excitation of the (2,0) band of the g system. This scheme is presented and discussed in the frame of its potential use in field instruments for the measurement of tropospheric OH concentration.

Abstract
In this communication we propose a new Laser Induced Fluorescence (LIF) scheme that allows the simultaneous detection of OH and NO by a single laser set-up. OH is detected by the Second Harmonic (SH) of a dye laser tuned to the (0,0) band of the 3064 Å system, while its Third Harmonic (TH) is used to detect NO through excitation of the (2,0) band of the g system. This scheme is presented and discussed in the frame of its potential use in field instruments for the measurement of tropospheric OH concentration.File in questo prodotto:
