Product Description

Study of Absorption Spectrum of Iodine vapour

Aim:- To study the absorption spectrum of  Iodine vapours & also calculate

(i) Electronic Energy Gap,
(ii) Vibrational Energies  &
(iii) Force Constant for excited states.

Setup Contains:-

  • A Spectrometer 6 Inch.
  • Long Absorption Glass Tube & Filament.
  • Light Source.(Mercury Source)
  • Diffraction Grating.
  • Spirit Level.
  • Power Supply for iodine tube.
  • Suitable Stands.
  • Connecting Leads
  • Reading Lens.

Formula Used:-

The following formula is use for calculation

  • For Electronic Energy Gap:-  E1 = hcv1 .
  • For Vibrational Energy:- E2-E1= hc v.
  • For Force Constant:- k = 42 m`(cv)2.
