With The Power And Range Of Modern Pulse Spectrometers The Compass Of Nmr Spec Troscopy Is Now Very Large For A Single Book-but We Have Undertaken This. Our Book Covers The Periodic Table As Multinuclear Spectrometers Do, And Introductory Chapters Are Devoted To The Essentials Of The Nmr Experiment
## Abstract By means of ^27^Al, ^1^H, ^17^O and ^13^C NMR spectroscopy the structure of the methylaluminoxane (MAO) cocatalyst of KaminskyβSinn catalysts was investigated. We have found that the ^27^Al NMR resonance line of MAO is extremely broad at room temperature (Ξ΄ β 60, ΞΟ~1/2~ 50 Β± 10 kHz). A
