Atomic Spectroscopy

Atomic Spectroscopy                           Suzanne Rakes Chemistry 2 Lab Dr. Seelbinder February 19, 2002         Data                   The info in the optic kick graph shown higher up contains the darn points of atomic number 80 (series 1) and atomic number 36 (series 2) disceptation readings in mm. and their wavelength in nm. The quicksilver and krypton wavelengths were frame by estimating where the alter were on the spectrum and referring to the liberation that was tending(p) up for the values. The line readings were interpreted from an average of the three or four-color bands on the continuum spectrum shown when expression at done the optical revile spectroscope. Shown beneath is a graph of the line readings and average of the colourize that were seen when looking through and through the optical rail.

The 1/lambda is the contrary of the Hydrogen wavelengths. The hydrogen wavelengths were found by putting the line readings into the mercury and krypton slant equations given from excel. (Calculations shown below) Calculations (Refer to graphs and graphs shown above) Mercury y = 59.375x + 64.789 59.375         x 7.05mm. + 64.789 = 483.4nm. 59.375 x 9.95mm. + 64.789 = 656nm. 59.375         x 6.35mm. + 64.789 = 442nm. krypton y = 60.942x + 46.972 60.492         x 7.05mm.+ 46.972 = 477nm. 60.492 x 9.95mm. + 46.972 = 653nm. 60.492         x 6.35mm. + 46.972 = 434nm. Average of wavelengths 480.2nm. 655nm. 438nm (Refer to Rydberg graph and chart shown above) Color         1/n2         1/lambda Red         1/9 = 0.111111111         1/655 E-9 = 1526717.56 Green         1/16 = 0.0625         1/480.2 E-9 = 2082465.64 Violet         1/25 = 0.04         1/438 E-9 = 2283105.02 per centum fallacy = actual - nonional / actual x nozzle candy = % 1.076414 -1.096776 / 1.076414 x ascorbic acid = 1.

89% ( rough 2% erroneous belief) treatment/Results         The percent fracture was about 2%. Our wavelength values for Krypton and Mercury were estimated fit in to our handout of given wavelengths. They were actually compressed to the actual wavelengths of Mercury and Krypton. This is known by looking at the percent error and seeing how finis it is. The ramp equations obtained from Mercury and Krypton was lend oneself to find the wavelengths for Hydrogen. This is in like manner a reason we know the wavelengths were close to the actual wavelengths. You can also tell that this was a successful experiment by study the Rydberg Equation (-1.096776) to the equation given from excel calculations which was ?1.076414.         When looking at the light lamp through a squ be control control grid all of the colourize of the spectrum were shown provided orangish. This could perhaps be that the gas gratuity in the fluorescent lamp gives sour an orange color and that could be why orange was not seen. Then a chemical formula light with disconsolate coverings were observed. The colour in seen when looking through the grid are: dismal covering-all colors of spectrum shown, blushing(a) covering-all colors shown, xanthous covering-green, yellow, red, slightly purple, grisly red covering- red, yellow, green, purple. Note: Observations of the continuum spectrum are shown above in the dodge of Mercury, Krypton and Hydrogen. The bands of color observed are noted in this table.
