They are: a2 = \u2013 218.569 \u00b1 0.004 Mc\/s, a1 = 4.738 \u00b1 0.036 Mc\/s, a2,1 = \u2013126.6 \u00b1 2.0 Mc\/s, a1,0 = \u2013 91.7 \u00b1 7.2 Mc\/s, b2 = \u201310.438 \u00b1 0.030 Mc\/s, b1 = 5.199 \u00b1 0.090 Mc\/s. These results confirm the values of a2 and b2 reported previously by Kamper, Lea &amp; Lustig 1957. Measurements have also been made on the excited level of the ground 2P multiplet of 19F. They yield: a\u00bd = 10244.21 \u00b1 0.03 Mc\/s, gJ (J = \u00bd) = 0.66561 \u00b1 0.00003. An analysis of the magnetic hyperfine constants in the ground multiplets of 17O and 19F shows that in neither case do they yield consistent values for the two parameters &amp;lt;r-3&amp;gt; and |\u03c8(0)|2 usually associated with magnetic hyperfine structure. All measurements of hyperfine structure in these multiplets are consistent, however, with the requirements of LS coupling theory which introduce a third parameter into the magnetic hyperfine operator. The discrepancy is attributed to polarization effects, other than spin polarization of the core s electrons, brought about by the exchange interaction between electrons.<\/jats:p>","DOI":"10.1098\/rspa.1965.0126","type":"journal-article","created":{"date-parts":[[2006,12,18]],"date-time":"2006-12-18T17:59:10Z","timestamp":1166464750000},"page":"581-596","source":"Crossref","is-referenced-by-count":153,"title":["Hyperfine structure in ground multiplets of 17O and 19F"],"prefix":"10.1098","volume":"285","author":[{"given":"J.
