<dt>Description</dt>
<dd>The ESR natural spectrum of humic-free speleothem calcite single crystals in the region of g = 2.0000 is a composite of lines from 4 radiogenic species, in addition to Mn&lt;sup&gt;++&lt;/sup&gt; lines. Laboratory irradiation causes appearance of three more species. Use of isotropic F species (g = 2.0003) for dating is possible if specific cautions are followed.</dd>
