NMR Reference Spectra...

This page is dedicated to the display of useful NMR spectra from ¹¹B experiments. If YOU have any useful spectra for boron chemists around the world to share please e-mail them to boronweb@chem.leeds.ac.uk

The following spectra were recorded on a Brucker ARX250 NMR instrument of magnetic field strength 5.875 Tesla. Measurements were made at a ¹¹B observation frequency of 80.25 MHz and a ¹H observation frequency of 250.13 MHz. Protons were decoupled at 250.13 MHzusing the composite pulse decoupling sequence WALTZ16.
