Introduction :- 



We know that scattering of light Nobel Prize given by CV Raman where scattering of light have to two types that is elastic and inelastic collision. CV Raman is Indian scientist. 

Elastic collision means no change in energy this is called as rayleigh scattering. 

Inelastic collision mean exchange of energy this is known as Compton effect. 

Raman spectroscopy deals with rotational and vibrational spectroscopy. 

Quantum theory of Raman effect that is Raman scattering could be understood in the term of Quantum Theory of Radiation Photon can be imagine ate to undergo collision with molecule. 

E= hv 

Photo collision with molecule buy inelastic collision and elastic collision. 

  1. Anti Stokes line
  2.  Rayleigh
  3.  Stokes line

Radiation can be scattered with a frequency lower than of incident beam is referred as strokes radiation while that of higher frequency is called as anti Stokes radiation. 

The molecules can gain or lose amount of energy in accordance with the quintal laws that is why its energy juice must be difference in energy between two of its allowed state.

Introduction:- 

ESR can be shown by one or more number of the unpaired electrons is called primary condition. 

  1. H atom Oxygen( Two unpaired) and NO2. 
  2. Radical for example carbene. 
  3. Transition metal ions that is 1 to 5 unpaired electrons
Many Organic Reaction can take this free radical mechanism example is polymerization reaction.

Selection Rule of electron transition :- 

If a photon light of the right frequency is absorbed by an electron,the electron jump to a higher frequency,if the electron releases a photon of light it will be jump to a lower energy state. 


Certain transitions are more likely to occur than others.The ones that have a high probability of a occurring are called the allowed transition while the ones that are less likely take place are called forbidden transitions


In quantum mechanics a set of rule exist known as the selection rule that and the allowed transition


Δl=±1,Δml= 0,±1


These rules tell us that electron cannot jump between two orbitals that differs by more than one orbital quantum number. 


From the selection rule the electron can jump from any of 2P orbital to 2s orbital


But notice that electron cannot jump between two P orbital because Δl= 0.

Some  question arise by JEE main aspirant


Average student crack Jee 2022:- 

Yes an average student can crack he/she provided he is ready to work hard with consistency there have been many average students who cleared with good ranks in the past year. 


JEE 2022 to be more competitive:-

The level of competition in 2022 will be no I think because many students are giving up as they are unable to attend classes in offline mode due to the lockdown by covid-19 because online classes were not affected, I think of an offline class is more better than online classes.

Selection Rule Of Rigid Diatomic Molecule



∆J = ±1

This rule says that when schrodinger wave equation show that for this molecule we consider transitions in which J change by one unit all the other transition being spectroscopically forbidden.

For Heteronuclear diatomic molecule are microwave active molecule i.e HCl, HBr, CO, NO etc

For Homonuclear diatomic molecule are microwave inactive molecule i.e H2, Cl2, N2, O2 etc
