We present several high-resolution (R ˜ 60,000) spectra of both classical and weak-line T Tauri Stars (cTTS and wTTS) located in the Chamaeleon I (D ≃ 140 pc) and TW Hydra Association (D ≃ 55 pc) star forming regions. Several stars, both cTTS and wTTS, possess an emission feature that can be associated with the v=1-0 S(1) H2 transition at 2.1218 μ m. These emission features match well with those of our previous detections of H2 from cTTS, GG Tau A and LkCa 15, in Taurus-Auriga and a wTTS, DoAr 21, in Rho Ophiuchus in FWHM and intensity. We conclude that the H2 emission observed towards these sources is also quiescent and is most likely located in a disk orbiting the young star.
