title: Laser two-photon ionization spectroscopy: a new method for real-time monitoring of atmospheric pollutants.
abstract: Laser two-photon ionization spectroscopy is proposed as a selective and sensitive method of monitoring atmospheric pollutants in situ. The technique is demonstrated in the laboratory for a prototype molecule, aniline, in air at 1 atm. Advantages over existing laser-based methods are discussed, and an ultimate detection limit of <1 part in 10(11) is estimated using currently available technology.
