unlimited thanks mam....q ki ap free me padha rahi ho pehle badme apna coaching kholne wali ho q ki me coaching classes join nahi kar sakta isliye ....thanks a lot....
U r master in every topic....mozza aaa gaya....I hope if everything happens as I want then it is the 3rd topic which will be on the way...love and respect from assam
At 29.33, the example that you took mam(pyrazine) contain 2 nitrogens also which are epr active so their contribution should also be there. Will there not be 25 lines? [2*4*(1/2)+1][2*2*1+1] (First part for Hs and 2nd for Nitrogen)
Thank you so much Jyoti. I am also a pass out of DU (2012-2014). I completed PhD and now studying for Gate. I have been away from the topics for a long time. But your videos have been it very easy for me. Very well explained and problm solving is the best part! Thanks a lot. Very helpful 👍
In H2 cation radical I think I is the nuclear spin. Splitting is due to interaction between electron spin and nuclear spin of proton ( Hyperfine splitting)
Thanks mam .... actually mujhe bhut khusi hui kyuki mai ishi ko pad raha tha aapka lacture dekha bhut help ....mam csir net ke har topic ki series vice video bnao ... bhut help ho jayegi..... thanks again
mam Why relaxation time ∆t is low in ESR or EPR, we can take this as high for sharp signal then we have no need for first derivative of I value... answer please 🙏
It's very helpful your channel in the period of lockdown I am going to watch your vedio one by one Starting from inorganic spectra Thank you madem🙏🌹🌹🌹🙏
Ma'am I've a doubt. In case of ethyl radical, you showed splitting for CH2 part first (1:2:1 -- 3 lines) then further splitted those 3 lines into 4 lines each due to the CH3 part In the last example of D2CH radical, u splitted D2 part first and then splitted those five lines further due to the H part. My doubt is - how to decide which part to split first ? Is there any rule for that or reverse also can be done?
In case of ethyl radical was with CH2 hence we always prefer the one having radical.... In second example radical carbon was attached to both the elements hence the one with high I value is preffered for splitting.
In CD2H radical why did deuterium split the spectrum first and then subsequently H comes? Why can't it be the other way around? Won't the coupling of electron spin with a 1/2 species be greater than that with a 1 species?
there is biggest confusion for me EPR part 1 ki vedio k 2nd last example me Nitrogen 'N' ki spin se hue splitting kyu nahi considered ki gayi jisme signals 5 arhe h agar N se splitting hoti to signal kuch or ate . Agar apne isliye considered ni ki kyuki N(15) ki natural abundance 0.37 hoti h to phir part 2 video k first question k 2nd no. NH2 hai jisme apne no. of line nikal ne k liye N ki bhi spin considered ki gayi h please help me out. and please reply fast..
