The hyperfine structure of the {sup 2}S{sub 1/2}-{sup 2}D{sub 5/2} quadrupole transition at 674 nm in {sup 87}Sr{sup +} has been observed. The ion was confined in a Paul trap and cooled using laser radiation at 422 and 1092 nm. The quadrupole transition was observed by monitoring quantum jumps in the 422-nm fluorescence. The odd isotope of strontium has 'clock' transitions independent of the first-order Zeeman shift and the {sup 2}D{sub 5/2} state hyperfine structure constants have been determined as A{sub D{sub 5/2}}=2.1743(14) MHz and B{sub D{sub 5/2}}=49.11(6) MHz. Standard uncertainties have been added in parentheses. These values allow the second-order Zeeman shifts to be calculated. The {sup 88}Sr{sup +}-{sup 87}Sr{sup +} isotope shift for the 674-nm quadrupole transition has been measured to be 247.99(4) MHz.
