This completes my spectroscopy..thank you.. With the end of my sems.. chemistry would take it's leave..again a fresh crop would get this subject...they would type "spectroscopy engineering chemistry"...if they found this series...then life's easy for them. The moral: a single nice explanation serves generations of students..helping in their journey...i bet it feels incredible as a professor...someday i wish to do this as well.🌞🌞
Thank You So Much Ma'am Spectroscopy khtm hui aapke saare lectures dekhe ma'am sb kaafi ache se smjh aaya i hope mere exams me yha se questions aaye aur mai unhe confidently answer kr pau thanks a lot ma'am🙏🙏🙏🙏❣❣❣❣
Superb ma'am ❤ Ma'am I've watched all 3 lectures of your NMR spectroscopy and understood nicely. Is it really sufficient? If yes, then I'll revise again but if not, can you suggest what else can I do after studying those?
very good playlist of spectroscopy just missing some detail of numerical types of question other than for theory it is best writing this after my sem exam thanks maam
mam video lectures are great but there is one problem .... i.e, i dont have notes of these topics so what will i write in exams. so mam if u have notes of these units kindly share it with us .....HUMBLE REQUEST....
ans= 2:7:1 Ma'am like in example = CH3-CH2-CH2-OH what will be splitting of second CH2 from left....triplet of quad or quad of triplet....isme confusion hai ma'am
why the ans of last ques in video is not 2:7:2???????? since on last ch3, ch is also attached and we should count h of ch so ans should be 2:7:2 pls tell this maam
Mam Hmare college mai bhi aur ek do utube videos mai maine yahi dekha hai ki Jo centre vale proton pe splitting nikalte hai toh ye use karte hai (N+1)*(n+1) Please clarify

Thank u so much mam for these awesome lectures of spectroscopy ❤ These lectures helped me a lot !!
Glad to hear that
Hats off Ma'am,
best explaination..
Thx u so much
@@chemistrybydr.anjalissaxena Ma'am There was a numerical based on NMR (To calculate Chemical Shift) in last yr's exam.
How to solve such a question?

Glad you think so!
very well explained mam ache se smjh aagya

The last answer : No. Of signals = 3 and splitting 2 : 7: 1 ........is it right ma'am??
yup bro it's right
2:7 :1answer of last question
Thank you ma'am ji ❤❤❤🙏🙏🙏
Most welcome 😊
MA'AM in CH3-CH2-CH3 the splitting of CH2 will be according to (2n+1) or (n+1) only..? We were taught of (2n+1) according to which splitting is of 13.
very good playlist of spectroscopy just missing some detail of numerical types of question other than for theory it is best writing this after my sem exam thanks maam
Noted
In the last compound, i have found two types of signals ,mam
Mam , upload a playlist on organic reactions and synthesis of a drug molecule .
Our mid sem- paper are in 4 or 5 days.
Only this one is left.
Your explanation is amazing ma'am
Thanks a lot 😊
Nice video

Correct. 3:6:3:1
I think ch2 ki 12 hogi 4*3
why the ans of this is not 2:7:2???????? since on last ch3, ch is also attached and we should count h of ch so ans should be 2:7:2
@nityagupta2085 because CH is not considered as neighbour of OH ..
(Only connection with C-C bond is considered as neighbour not C-O bond )
crystal clear
Thx u
why the ans of last ques in video is not 2:7:2???????? since on last ch3, ch is also attached and we should count h of ch so ans should be 2:7:2 pls tell this maam
In this ques. ch having same neighbor so ans. Is 6+1=7 and oh=1
Mam kuch questions aur karwa dijiye No of Singals and splitting predict karne ke
Ok
Crystal clear 😌

Different theorms are there but at the time of evaluation both are considered.
