H 3 + is ubiquitous in space and may exist there also in the triplet state. Despite of itsfundamental importance, triplet H 3 + has not been observed yet or studied by laboratoryspectroscopy due to the lack of complete theoretical predictions. While a couple of qualitypotential energy surfaces and results of rovibrational calculations have been reported (seeRef. 1 and references therein), no dipole surface has been obtained yet that would permitthe estimation of the oscillator strength of the fundamental bands. Such work is now inprogress in our laboratories. Preliminary results will be presented at the conference.References[1] A. Alijah, A. J. C. Varandas, Phil. Trans. R. Soc. A 364, 2889, 2006[2] V.
