In the previous chapters, we explored the concept of electron spin. We began by introducing the idea of spin and then clarified that electrons do

181. Spin Multiplicity (1).
In this post, we are going to learn an important concept in photochemistry—spin multiplicity. This concept plays a critical role in understanding how molecules behave
180. The electron spin (2).
In the previous post, we familiarised ourselves with the concept of electron spin. We learned that spin is an intrinsic property of an electron –
179. The electron spin (1).
In the previous post, we concluded the discussion on the Franck-Codon principle. This principle states that the molecule’s geometry remains unchanged during an electronic transition.
178. ABSORPTION OF RADIATION(9) – FRANCK -CODON PRINCIPLE(3).
In the previous post, we studied the Franck-Codon principle, which states that an electronic transition takes place so rapidly, that a vibrating molecule does not
177. ABSORPTION OF RADIATION(8) – FRANCK -CODON PRINCIPLE(2).
In the previous post, we wondered – DOES CHANGE IN THE ELECTRONIC LEVELS BRING ABOUT CHANGE IN THE VIBRATIONAL ENERGY LEVELS TOO? In this post,
176. ABSORPTION OF RADIATION(7) – FRANCK -CODON PRINCIPLE(1).
Understanding the molecular vibrations is very interesting. To locate the molecule in space, we need to predict its behavior. When we try to find the
175. ABSORPTION OF RADIATION(6) – MORSE POTENTIAL(2)
After learning the concept of Morse’s potential in the last post, let us start this post by getting to know the man behind this concept
174. ABSORPTION OF RADIATION(5) – MORSE POTENTIAL
We concluded the last post by stating that molecules are anharmonic oscillators. In an anharmonic oscillator, the restoring force(F) is no longer proportional to the
173. ABSORPTION OF RADIATION(4) – BY MOLECULES.
In the last post, we concluded that only the vibrational and electronic energy of molecules, need to be considered while constructing a molecular energy diagram.
172. ABSORPTION OF RADIATION(3) – BY MOLECULES.
From this post onwards, we begin discussing the absorption of radiation by molecules in detail. In post 170, we discussed how absorption by atoms and
171. ABSORPTION OF RADIATION(2) – BY ATOMS.
In the previous post, we learned why energy level diagrams in atoms and molecules are different. We can summarize the post by concluding that, in
