Abstract
Computerized microwave pulse generation and detection with subsequent Fourier transformation of electron spin echo envelope modulation spectra has been used to measure the small 6,7Li nuclear superhyperfine and quadrupole splittings of a lithium‐compensated titanium(3+) center in single crystal α‐quartz. Comparison of the 7Li hyperfine matrices Ā determined from standard cw‐EPR and from ESEEM show excellent agreement. The precision is better by an order of magnitude for the latter, with uncertainties on the order of one part in a thousand. Use of a three‐dimensional display technique yielded the relative sign of matrices Ā and Q̄ for 7Li.Keywords
