Spectroanalytical Methods

Spectroanalytical methods measure the wavelength and intensity of radiations that are either emitted or absorbed by a molecular or atomic species. These methods are useful for evaluating the electronic or atomic arrangement of the molecules of a given analyte.

In a FranckHertz experiment on sodium atoms, the first excitation threshold occurs at 2.103 eV. Calculate the wavelength of emitted light expected just above this threshold. (Note: Sodium vapor lamps used in street lighting emit spectral lines with wavelengths 5891.8 and 5889.9 Å.)

In high-temperature sources, sodium atoms emit a doublet with an average wavelength of 1139 nm. The transition responsible is from the 4s to 3p state. Set up a spreadsheet to calculate the ratio of the numberof excited atoms in the 4s state to the number in the ground 3s state over the temperature range from anacetylene-oxygen flame (3000°C) to the hottest part of an inductively coupled plasma source (8750°C).

The maximum in the blackbody radiation intensity curve moves to shorter wavelength as temperature increases. The German physicist Wilhelm Wien demonstrated the relation to be max1/T . Later, Planck’s equation showed the maximum to be max=0.20hc/kt . In 1965, scientists researching problems in telecommunication discovered “background radiation” with maximum wavelength 1.05 mm (microwave region of the EM spectrum) throughout space. Estimate the temperature of space.

Give typed full explanation not a single word hand written otherwise leave it Which of the following statements are 'correct' regarding the fluorescence and phosphorescence emission processes commonly used in spectroscopy? I- Fluorescence and phosphorescence events are important emission processes that occur after the excitation of atoms or molecules with a thermal or chemical energy. II. In the photoluminescence processes called fluorescence and phosphorescence, a ray-excited species returns to its ground state by releasing its extra energy in the form of photons. III-If gaseous atoms are excited with any energy, the atom emits a beam with the wavelength that characterizes it, and makes fluorescent radiation. IV. It is possible for a light-excited atom or molecule to return to a lower energy level or ground state by heat transfer by collisions without emitting any rays. A. IandIII B. IandII C. II and IV D.
