Abstract [en]

The aim of the experiment is to find out which transitions induces Iodine by a green and a yellow He-Ne laser measuring the fluorescence spectra. The iodine molecule would be excited by a laser beam in a transition from ground state  X1Σg+ to excited state B3Π0+u. Matlab was used to calculate the possible transitions induced by the laser to find out the possible energy level and to simulate possible fluorescence spectra which were compared with the fluorescence spectrum obtained from the laboratory detection. According to the results, for the green laser, a possible laser addressed transition was identified to be from v''=0, j''=103 to v'=27, j'=104 . For the yellow laser the transition from v''=2, j''=186 to v'=17, j'=187 was identified.
