Optical Spectometry 10/26/07 The intention of this lab was to determine the identity of an unknown salt solution, based on its emission spectra and the measured emission spectra of known salt solutions, and to create a molecular orbital diagram for hydrogen based on its emission spectra.

As a form of practice for the salt solution tests, the emission spectra of a fluorescent light was observed, using the naked eye to estimate and record spectra values: Wavelength Relative intensity (brightest possible = 10) 610 8 590 4 545 9 490 1 435 7 The emission spectra of an incandescent light bulb was then observed and found to be continuous, producing on the screen of the spectrometer a swathe of rich color instead of individual lines. The following ranges of the spectrum were observed: λ 790-690 nm far red 690-640 red 640-605 orange 605 – 585 yellow --- The yellow, orange, and green areas of the spectrum all exhibited high intensity 585 – 510 green 510 – 480 blue 480 – 430 indigo 430 – 400
