isopropanol chemical shift

The lowest downfield at 1ppm are the 6 hydrogens of the methyl groups which are a doublet b/c they are next to the one hydrogen on the methylene. By: Search Advanced… New SDN Article: Mary Bluthardt PharmD, MBA: Young Pharmacist Profile. Note: In principle, you should be able to work out the fact that the carbon attached to the oxygen will have the larger chemical shift. Is it suppose to be doing this? Er... actually. That means that the peak at about 60 (the larger chemical shift) is due to the CH 2 group because it has a more electronegative atom attached. I just looked really close and it does appear that it is actually a septet. tel: 978-749-8000 800-322-1174 (USA) fax: 978-749-2768 cilsales@isotope.com 2 ContaCt InformatIon ContaCt CIL by Phone, Fax or e-maIL The CIL Customer Service Department is open Monday-Thursday 8:00 A.M. to 5:30 P.M.; Friday 8:00 A.M. to 5:00 P.M EST. nmr is fun man. The next downfield should by the hydroxyl hydrogen, which rapidly exchanges in an NMR solution and shows up not as a singlet (s) but as a broad small (bs) peak. It is very likely that it does not need any further discussion and thus bumping it serves no purpose. I can't figure out why this NMR is showing me a pentet for the lone hydrogen in the NMR instead of septet. This NMR stuff is really starting to piss me off. think of it as a puzzle. About the Ads. Tables of 1H and 13C NMR chemical shifts have been compiled for common organic compounds often used as reagents or found as products or contaminants in deuterated organic solvents. steps you need to take to apply to medical school, http://www.chem.ucla.edu/cgi-bin/webspectra.cgi/bp6/H?390,210, Need advice about competing future Pre-Req classes for Medical School. It may not display this or other websites correctly. Your reply has occurred very quickly after a previous reply and likely does not add anything to the thread. Most probably it should show up as a doublet of a triplet, but if you are looking at a real spectrum not a perfect one use in an organic text one of the peaks might be hard to see.

All they say is that a proton such as that will not couple other protons. Your reply is very long and likely does not add anything to the thread.

Actually the data you have sound about right. I'm just going to burn this worthless ochem book. You are using an out of date browser. Your message is mostly quotes or spoilers. Finally the most downfield will be the single hydrogen on the middle carbon, which is shifted so far downfield due to its proximity to the oxygen. Your message may be considered spam for the following reasons: JavaScript is disabled. The effect of this is that the chemical shift of the carbon increases if you attach an atom like oxygen to it. unless you hate puzzles...then you are in for hell. The chemical shifts (d) of solvent signals observed for 1 H NMR and 13 C NMR spectra are listed in the following table. Your reply is very short and likely does not add anything to the thread. The multiplicity is shown in parentheses as 1 for singlet, 2 for doublet, 3 for triplet, etc.
