The physics of microwave-burst emission is briefly examined to give the rationale for investigating polarization spectra. The instruments used to carry out the 9.4GHz and 7GHz circular-polarization measurements and the 5GHz Stokes-parameter measurements are described. A survey of the August 1972to December 1973period produced a table of 45bursts,from which some limited results were obtained. About 75to 80percent of all bursts are circularly polarized,with varying polarization over the 5to 9.4GHz range. For most bursts where the circular polarization pc increases toward the upper or lower end of the 5to 9.4GHz range,the total intensity I also increases in that direction. The few bursts having a pc sense reversal in the 5to 9.4GHz range also have a spectral maximum of I at roughly the same frequency. Some simplified explanations of the results are presented.
