B-11 QUADRUOPOLE COUPLING CONSTANTS IN TRIMETHOXY-BOROXINE AND N-TRIMETHYLBORAZOLE
Abstract
A Varian V-4200B NMR spectrometer was used to obtain broad band spectra of trimethoxyboroxine and N-trimethylborazole from which the B-1 nuclear electrical quadrupole interaction was measured. The Townes and Dailey method of analysis (Mirowave Spectroscopy, McGraw-Hill Book Co., Inc., N. Y., 1955) is used to estimate the electron configuration of these moleules. The quadrupole coupling constant, eQq/h, of B-11 for one excess p electron is taken as 5.39 mc/sec. In both compounds, the quadrupole interaction split the central transition, m equals 1/2 to - 1/2. A relationship between the derivative maxima, eQq/h and the asymmetry parameter, eta, is given by Silver and Bray (J. Phys. Chem. 29:984, 1958). (Author)
