Solving Spectroscopy Problems (Optional) 

thank u i have been looking unto different videos of spectrosopy but this helped me alot

For unsaturation u add for a hologen and subtract for a niteogen and ignore oxygen

Thank you. Though I feel that the 13C NMR is mostly useless. I have never once solved a spectral problem with that info as a crucial piece of info. Is there a good example where 13C NMR is key for a correct answer ?

Very very helpful!
