The block diagram (Fig 2) below illustrates the relationship between these parts. Fig 2 In your spectrophotometer, light from the lamp is focused on the entrance slit of the monochromator where the collimating mirror directs the beam onto the grating. When the UV/Vis is radiated to a molecule, we see an absorption. The wavelength at which the radiation is absorbed, provides an energy for an electrical transition. This electrical transition is from the stable highest occupied molecular orbital (HOMO) to lowest unoccupied molecular orbital (LUMO) which is the unstable antibonding orbital.
