- Can we calculate absorption maximum of a cyclic conjugated diene in spectroscopy? Yes, of course it can be done with the help of few empirical rules given by Woodward-Fieser.
Cyclic conjugated dienes can exist as homoannular or heteroannular dienes where the former shows more bathochromic shift than the later. But the molar absorptivity is more observed with heteroannular dienes.

Well explained... And really very helpful in my studies
Glad to hear that. Thanks for watching
@@egpat Go on making such useful videos 👍
Yes a big thanku sir ji😄🤓
i have watched more than 5 vidoes of spectroscopy on your channel, it very understandable with great concept buildup, you r really amazing Sir, Thank you so much
I can never get a better explanation than this. 🔥
Amazing very well explained ,Thanks alot sir for clearing all doubts 🤗 God bless you ✨✨✨
So far the best explanation I found on the youtube
It's amazing... Thank you so much.... Today is my paper and I'm able to calculate lambda max just because of you
Glad it is helpful. Thanks for watching.
Very very thank u sir... I'm totally confused about how to calculate... But after shown ur vedio it's very useful to understand....thanks alot
So far best video found for calculation of woodward fizer rules
Thank you very much. Very useful and clearly explained ❤️
Now this tropic is crystal clear to me. Your presentation is amazing, I cant understand this tropic from my professor.
Thank you very much SIR,
Glad it was helpful!
You made explanation simple and understandable.thank you so much it's very helpful.🌸God bless you 🌸🌸🌸
Thank You.The explanation is very useful to understand the calculations.
Happy to hear that. Thanks for watching.
I have no words to explain your efforts.
Just I'll say level. 💯

Well explained ma Sha Allah. God bless you
Very well explained sir. It is really helpful for me
Your way of explanation is understandable for me
I love this channel always my first resource to understand my curriculum. KEEP up a good work.
also I would like to ask you if you have time we want 31P NMR explanation
Thank you .
Thank u sir. Very clear explanation and easy to understand .
thank you so much! Finally I understood the calculations! :)
Glad it helped! Thanks for watching
Thanks for making these useful videos....your way of teaching are too good✨✨

You're welcome
Well explained, thank you sir
Tnx for english .. Video is really good. Clear my doubts
I finally understand what the exocyclic is referring to. I always thought it meant it had to be outside of EVERY ring😮
Very determinate and very much useful sir
Thanks so much. You made the explanation simple and understandable. It really helps because in the college my lecturer didn't explain it throughly.
Glad it is useful to you. Thanks for watching.

Well explained sir ..thanks
Excellent presentation ❤
it was amaizing. sir thank you so much.
Most welcome. Thanks for watching.
Outstanding understanding lecture... The way of understanding to the student was awesome👏👍... If u make video on calculations of lambda max of functional group attached to the ring it will be more helpful for us... Keep smiling and keep shining sir🙏🙏🙏
Thanks a lot sir very very helpfull
I understand your lecture clearly.Thank you
Glad to hear that. Thanks for watching.
Amazing lecture
You just cleared all my doubts, my lecturer din explain it well 😭

Thank u sir
Very useful
You are the best master
very well explained with lots of examples and proper animations (slides)..thank you so much. Have a great day.
but i have question.. what is the base value for an acyclic diene which is homoannular? Is it 260 nm?
Did you finish the video?
Clear video version made more easier than other videos
Best possible explanation the topic can have👏🙏
Glad to hear that, thanks for watching.
Well explanation,
👌
Nice work sir

感謝~~!幫助很大
Thank you so much Sir🙏🙏🙏
Hi thank you for the video!! the explanation is insanely clear, love it!!!! Still, i'd like to ask why the ring structure at 19:35 is considered as homoannular diene instead of heteroannular? Thanks!
Super explanation ❤️
Thanks a lot sir
Thanks a lot❤
Watched tis in 2024 and thanks alot for better explanation , much needed
Nice video ..
Nice explanation broh
Thankyou sir 🙏
Clear explanation 👍🤗
