Learn how to calculate NMR spectrum using gNMR program with an example of ethanol. Download the demo version from Adept Science's website or copy the old PC version, then follow step-by-step instructions to assign shifts and generate spectra.
E N D
Use of the program gNMR to calculate NMR spectrum Example: etanol: CH3-CH2-OH; see: http://riodb01.ibase.aist.go.jp/sdbs/cgi-bin/direct_frame_top.cgi Assign. Shift(ppm)A 3.687 B 2.61 C 1.226
Demo version of gNMR can be downloded from the web: • http://www.adeptscience.co.uk/products/lab/gnmr/ • Alternatively • an old PC-version can be copied via ÁK. • gNMR is to be found on PC computers in VRI-121
Type in appropriate values for ethanol: For example as: No protone n 1 CH3 3 2 OH 1 3 CH2 2 J=0 J=7 Hz J=0 Assign. Shift(ppm)A 3.687 B 2.61 C 1.226
