what if the peak start from 7 ppm not 0...is the way of reading it are still the same??

& if i tested unknown sample...how can i know the structure?

@mia140287 what are the peaks? Do you have a jpeg file?

lol. thought u were japanese. kinda stalked u a bit.

thanks so much for the vid. it was really clear

[Sarutahiko1]

@tiffany88ag its youtube, not stalking people is more inappropriate than stalking them. i lived in japan for three years.

thanks for the explanation. i have an exam on Monday and you just saved me....

@mikaryn ethyl ethanoate!!! perfect! quartet at 4, triplet 1 ish, carbonyl inductive effect whooooo

glad it helped thanks for watching

thank you so much! you made it really simple :)

I think it would help out if you added comment bubbles to the NMR readouts that correspond to the different functional groups you labeled (A,B,etc). I'm not sure which peaks go where

watched both parts .. veryyy helpful :) Thank u so much!!!!

@mia140287 This should not happen because it means you did not use a Zeroing agent usually (CH3)3Si. this will allow you to pleace it around 0 then create a downfield plane. Enjoy

love the video really good

[simysimss]

Very enjoyable thank you

I have a question. In my book,(Klein), they put a number above the peak and I can't find what this stands for. Thank you for the video.

interesting video and very informative

[JoelT23]

can someone explain.... i know it sounds simple but just baffled by this, the splitting in propanal.CH3-triplet, neighboring environment=CH2..CH2... quintet or quartet and a doublet, (2 splitting patterns?either side having diferent proton environments. now my idea at the moment would be that it would be a pentet. But thn with that coms spliting up the peaks into 2 diferentparts as they are different groups giving diferent shifts/ppm thing..basicly wht do with eitherside groupsbeing different?:)

very interesting thanks
