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 vector and the velocity direction). What is the value of the Doppler shift in MHz?

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 /...

Two water samples were analyzed for their copper content by atomic absorption spectroscopy. After 5 replicate analyses, the first water sample was found to have 12.6± 0.9 mg/L copper. After 6 replicate analyses, the second water sample was found to have 13.1± 0.6 mg/L copper. Is the copper content in these water samples significantly different? Report your answer in a full sentence, including all necessary information to explain how confident you are about your answer. Answer: Since the calculated t...

The amount of sodium can be determined in an apple using atomic absorption spectroscopy. 0.4326 g of apple was dried, heated at 700oC and chemically treated with a concentrated HCl solution and diluted to 250 mL. 10 mL aliquots were transferred to 50 mL flasks. Each was treated with a standard solution of Na+ at 25.0 ppm and analyzed using flame AAS. Construct a standard addition graph and calculate the weight percentage of Na in the apple. Na+ standard (mL)...

a) Horvat and co-workers used atomic absorption spectroscopy to determine the concentration of Hg in coal fly ash.22 Of particular interest to the authors was developing an appropriate procedure for digesting samples and releasing the Hg for analysis. As part of their study they tested several reagents for digesting samples. Their results using HNO3 and using a 1 + 3 mixture of HNO3 and HCl are shown here. All concentrations are given as ppb Hg sample. HNO3: 161 165 160...
