Collimated atomic beam, saturated absorption and two-photon spectroscopy are three methods of Doppler-free laser spectroscopy. (i) In each case summarize briefly the principle of how the Doppler width is reduced or eliminated , (ii) Which method (methods) collects (collect) signal from all atoms illuminated by laser beams? (iii) In collimated beam spectroscopy the probe laser beam with the wavelength of 0.5 μm intersects the atomic beam (velocity of 300 m/s) at the angle of 70o (the angle between the wave...

A new flame atomic absorption spectroscopic method of determining antimony in the atmosphere was compared with the recommended calorimetric method. For samples from an urban atmosphere, the following results were obtained. Sample No. Antimony found (mg m-3) New Method Old Method 1 2 3 4 5 6 22.2 19.2 15.7 20.4 19.6 15.7 25.0 19.5 16.6 21.3 20.7 16.8 Do the results obtained by the two methods differ significantly? Clear answer required please, showing which tests used

When an optical spectroscopic transition is measured, either by emission or absorption, a so-called lineshape of given intensity and frequency dependence is obtained. For any spectroscopy there exist quantum mechanical or other basic connections to all of the experimental parameters that determine the lineshape. List these experimental parameters and explain how they are related to the previously mentioned connections.

Atomic absorption spectroscopy was used to determine the amount of aluminum in a sample of sunscreen....

Atomic absorption spectroscopy was used to determine the amount of aluminum in a sample of sunscreen. A blank solution was measured seven times to determine the detection and quantitation limits of the spectrometer. The blank readings were as follows: 0.0086, 0.0107, 0.0095, 0.0103, 0.0113, 0.0104, and 0.0094 AU. Determine the signal at the detection limit and the signal at the limit of quantitation for this method.

Atomic absorption spectroscopy was used with the method of standard additions to determine the concentration of cadmium in a sample of an industrial waste stream. For the addition, 10.0 μL of a 1000.0 μg/mL Cd standard was added to 10.0 mL of the unknown solution. The results obtained are shown in the table. Absorbance Reagent blank 0.028 Sample 0.480 Sample plus addition 0.887 What is the concentration of the cadmium in the waste stream sample? c = μ g /...
