LRIS optical spectra of three T dwarfs, 2MASS J1237+65, SDSS 1346‐00, and SDSS 1624+00, normalized at 9200 Å. Data for SDSS 1346‐00 and 2MASS J1237+65 have been offset vertically by constants of 2 and 4, respectively. The following common features are shown: the K I resonant doublet (broadened to ~7300–8100 Å), Cs I (8521 and 8943 Å), CH4 (8950 Å), and H2O (9250 Å, stellar and telluric). The 0‐0 A4Δ‐X4Δ band of FeH (9896 Å) in SDSS 1624+00 is also shown. Hα at 6563 Å is unambiguously seen in 2MASS J1237+65.
