Wikipedia
Nuclear magnetic resonance (NMR) is a physical phenomenon based upon the quantum mechanical magnetic properties of an atom's nucleus. All nuclei that contain odd numbers of protons or neutrons have an intrinsic magnetic moment and angular momentum. T...

Questions & Answers
How can you prove that p-methoxycinnamic acid has a trans configuration using H NMR spectra?
There is a pair of doublets due to coupling of the two vinylic protons in the H NMR spectrum of p-methoxycinnamic acid; one is centered at ~6.4ppm and the other at ~7.6 ppm.
You need to measure the distance between the closely spaced lines (J values). Trans and cis J values will be different
Does anyone know of a free online database for P (H) NMR, and F (H) NMR spectra analysation, inorgan
Does anyone know of a free online database that contains spectra analysation of P (H) NMR and F (H) NMR spectra. I am trying to find a database where I can enter an inorganic complex, and get the spectral analysation data. There are some good online databases, but I have yet to find databases with P (H) NMR and F (H) NMR data.
I hope that there is someone out there with knowledge and help!

You could try this website it has some downloadable software and NMR links etc. I havent tried them all but a couple are good, not sure about for P (H) NMR and F (H) NMR) though. I will ask my friends this weekend and get back if any possitive links
I had lots of trouble looking for databases with prediction until my research group purchased the Chemstation software with predictable NMR feature, but its expensive.
Does anyone know a link for free H-NMR spectra?
All of the sites I've found do not have the compounds i'm looking for or they are trying to charge me.
I'm specifically looking for the spectra for limonene, beta-myrcene, and alpha terpinene.
Stacey, that is a great site, but i already knew about it and there is no HNMR for the compounds i needed. just IR and CNMR. :( doyou know of any others?
Yeah, I have found all of the compounds on the site (i did have to type the chem formula for those that did not recognize the common name), but there is no HNMR for them. oh well thanks anyways.
sure do....google SDBS. An amazing spectral database!
Sorry; I don't. There are spectral reference books available and they should be located at you university library. Have you tried typing the molecular formulas of the compounds that you are looking for into SDBS?
Do you have chem draw? The program can predict H NMR spectra for you.
