✦ Synopsis

B NMR spectroscopy: Spectra of amino borane samples were recorded on a Varian Unity Inova spectrometer operating at a 1 H frequency of 800 MHz with a 4-mm 3-Ch Doty MAS probe. For the Bloch decay experiment a 200-kHz sweep width, a 5-ms 908-pulse for 11 B (with and without % 30 kHz decoupling), and a pulse delay of 5 s were used. Samples were spun at 15 kHz then cooled to 10-20 8C, and 128 scans were collected for each spectrum.
