Laser Excited Fluorescence Methods in Analytical Chemistryo that atomic fluorescence methods should be capable of detecting 10.. or 60 atoms/cm. concentrations. A classic experiment by Fairbanks, Hänsch, and Schawlow demonstrated detection of 100 Na atoms/cm. in a heated cell (3).

Introductionery controlled way (comp. Fig. 1). This type of single-level chemistry has developed into an important aspect of laser chemistry, although it has become more fruitful for diagnostic and analytic than for synthetic chemistry.

Introduction of chemistry were formulated by physicists. These envisaged the use of single quantum excitation in reagents to lead to very specific products in a very controlled way (comp. Fig. 1). This type of single-level chemistry has developed into an important aspect of laser chemistry, although it has beco

Multiphoton Ionization in Analytical Chemistryr fission of Cf were detected within a proportional counter after they were ionized by a dye laser tuned to a resonant transition. The ionization continuum was reached after a second photon was absorbed by the excited Cs atom. Since then, the resonance enhanced ionization methods have been extended

Nonlinear Spectroscopic Techniques and their Applications to Analytical Chemistryld associated with a propagating electromagnetic wave (1–9). At low electric fields, there is a linear relationship with the susceptibility, χ., defining the proportionality constant. High fields can be created by focusing lasers to small areas where the fields become comparable to the binding force

Laser Measurements of Trace Gases in the Atmosphere and in the Laboratoryod are discussed in detail. In a second part single-atom detection in the laboratory is reviewed, and as an example an experiment is presented in which collision processes of single atoms were studied..In the past decade the detection of small concentrations of atoms and molecules in the atmosphere
