We report new measurements of the 5p<sup>5</sup>(<sup>2</sup>P<sub>3/2</sub>)nf [3/2]<sub>1,2</sub>, [5/2]<sub>3</sub>, [7/2]<sub>3,4</sub> and [9/2]<sub>4,5</sub> (6≤n≤40) Rydberg spectra of xenon using a Nd:YAG pumped dye laser in conjunction with an optogalvanic detection technique. A DC discharge in a cell run in electrically quiet mode populated most of the levels based on the 5p<sup>5</sup>(<sup>2</sup>P<sub>3/2</sub>)5d configuration. Well developed Rydberg series have been observed due to excitations from each of the collisionally populated 5p<sup>5</sup>(<sup>2</sup>P<sub>3/2</sub>)5d [1/2]<sub>0,1</sub>, [3/2]<sub>2</sub>, [5/2]<sub>2,3</sub> and [7/2]<sub>3,4</sub> levels. The J-value assignments have been established on the basis of the selection rules in the jK-coupling scheme.
