Started Understanding the Subject before one night of the exam... At 1:55..🙂

Pass hua bhai??

[@animefreak6960]

Waooo waoooo waooooo mind blowing explanation, itna easy karke apne jo explain kya hai na guru ji , apke asirwad se exam dene ja raha hu , khus raho sir💕

[@nitikaaversatileworld4928]

Can you please clear once again...In book triplet state is for phosphorescence. Because of opposite spin takes more time

[@mangogaming3137]

yes

[@sdrik2001]

New vedio kab ayegi

[@punjabiVlogger4878]

Yes you are right...

[@manishagome9470]

Thanx u Wonderful teach
Clearly Samj me Aagya ab
waise sir covid ki wajh se classes online chli thi to clearly samj me nhi aarha tha
ab ek dm douts clear ho gya sir 👍

[@mdumer8344]

Very knowledgfull Sessions of your teaching ..
Thanks a lot Sir for making us videos in a very simple method...

[@arindamroy6907]

sir, you teach us this lesson nicely. but I have a doubt, in my book the phosohorescence is shown as the light reflect from triplet state and comes to ground state. and the direct shifting of light from excited state to ground state is named as fluorescence . is this right or wrong ? except this ,the total lecture is easily understandable. thank you

[@shallusharma8997]

The instantaneous removal of radiation from first singlet excited to ground singlet state is fluorescence and slow removal of radiation from first triplet excited state to ground singlet state is phosphorescence

[@thehardy9145]

You are right man

[@rhushikeshdesale1416]

Yes

[@mangogaming3137]

u r right

[@r_d_sdevils9042]

12.53 pe wrong hua hai .
Energy emitted from triplet state to vibrational ground level is called phosphorescence.

[@harshpharma]

Haa

[@movizz]

Yes

[@shikshaeverything]

Love you sir jii 😍😍😍🌺🌺🌺🙏

[@vaibhavgosavi6011]

*Wrong* bola sir aapne ....
Right answer is👉:- If energy directly come from excited state to ground state is called as fluorescence
And if energy come from excited state to triplet state then ground state is called as phosphorescence in this process take longer time than the fluorescence

[@KclTutorials]

Kindly check again in your book

[@vaibhavgosavi6011]

Thanks a lot sir for Such wonderful video😊

[@ameen0201]

Sorry sir u have done small mistake,Triplet state- phosphorescence
10-2 to 100 sec app.
Because emission of energy relax from Triplet excited state to ground single state. 👍🏻

[@shubhamhumbe5]

Awesome sir thoda sa time nikal kar lecture banate raho sir

[@MohitKumar-bv1dw]

KCL sir taught wrongly in the end of the video.
12:10 to 13:45
Correction is here:
When an electron comes from a singlet excited state to a triplet excited state, it undergoes a process called intersystem crossing. This is a non-radiative transition that involves a change in the spin of the electron. The triplet state is more stable and longer-lived than the singlet state.
When the electron goes from the triplet excited state to the ground singlet state, it produces phosphorescence. This is a radiative transition that also involves a change in the spin of the electron. Phosphorescence is a type of luminescence that persists after the excitation source is removed.
On the other hand, when the electron goes from the singlet excited state to the ground singlet state, it produces fluorescence. This is a radiative transition that does not involve a change in the spin of the electron. Fluorescence is a type of luminescence that ceases as soon as the excitation source is removed.
I hope this helps you understand the difference between fluorescence and phosphorescence.
