Thank you doctor so much. May l know please how can select column ( length and diameter) is this depend on amount of sample .becauae some times i have like 0.1 gram of sample and some times 0.8 gram or above I have confuse which colum to use or depend on spot on TLC. If this please how ? Thank you doctor

Assalam. Thank you doctor .If my sample does not dissolve in any solvents such as; methanol, chloroform, DCM , acetone how can I do please to dissolve it and pour it in column?

Wow, very educating and nice presentation.

asslam prof. please: I have a question about programs or software like mnova NMR , can postgraduate students or researchers use it for publication or will be rejected. and please could we see in your channel how can assignment atoms in spectra proton and carbon NMR. in case strucures containe substituents in differern position .thank you so much prof

Thank you so much prof . This is nice channel . Pleaae prof we need more like this and Molecular Dynamic. Jazak Allah Khayr

Allah blessed u please in English.tq

Good job thank you doctor. Please do u have same this training in English please.tq

MashaAllah. Dr. Please could explain us how can determent atoms for proton and carbon .(assingment) if we have structure example containes two rings with different substituents in different position. How can i know this atom belongs to this value .without using 2D NMR because it is expensive.

Clearly explained. Thank you very much Dr. Mohamed Nurul for this self explanatory video.

assalam, thank you Dr. please could explain lectures aboit how can determine chemical shift for atoms on structure containg two aromatic rings with substituents, how can we know chemical shift, tq

assalamualaikum please doctor we need one more lecture for how can interpret proton and carbon 13 NMR for compounds containe benzen or heterocyclic ring because we could not interpret which signal belongs atom, how can we know that, is it using splitting or what, i mean without using 2D NMR if we have a lot of compounds, the 2D NMR is expensive, please need your help and your experence. Allah bless you

thank you Dr, please we need another lectures about assignment proton and carbon NMR, also i have question, please if you use Mnova NMR could please explain it using examples< Allah bless you

salam doctor and Ramadan mubarak, please could show and explain to us if i have spectrum H NMR how can assignment each protons using j-coupling if i use this method will be good to interpret protons NMR also how about carbon NMR, many thanks

salam doctor and Ramadan Kareem. May please another examples for Structural Determination , Allah protect and bless you in this holy month

Salam Doctor. Allah bless u , Could please give us one more by using same your style . tq

🌹🌹👍👍👍👍👍🌹🌹 thank you

assalam and good morning Dr. please could you explain another examples by using your method. because i did not see on youtube any Doctor in organic chemistry like your method, it is excellent and An understandable method for beginners

Salam prof, please give us more example like your style, your method and style for interpretation by using 2D is very nice. Thank you

JazakAllahu Khair

Assalamalikium Dr.Mohamad. thank you a lot, your style for assignment for structure is easy and very nice. please Dr. could please another video . Alhamdollelah I finished my Master degree in organic but I find problems i ca not assignment values for each atom and signals in proton , carbon , COSY, HMBC and HMQC NMR. Alhamdolellah I found this video and i found your channel is excellent. May Allah blessed you and protect you, give us another video,Thank you

Thank you prof. this is the best explain for NMR and how can Interpretation of peaks. Please prof, we need more examples please same this. thank you again

Will the results be approved by the journal or should they be interpreted according to experience?

Thank you Dr. Can i use the software like mnova nmr or acd lab to interpret my result for publish article .

Thank you Dr. Also i have this question: is hexane only we use it to dissolve siica gel ?

Assalamalaikium. Thank you doctor. Please I have some question : what is the meaning of silica gel : n-hexane 1: 30? Is this ratio mean 1 gram silica gel to 30 ml of hexane
