We report the first detection of H-2 absorption profiles of LMC gas on the line of sight to star 3120 in the association LH 10 near the emission nebula N 11B. Transitions found in the Lyman band are used to derive a total column density N(H-2) = 6.6 x 10(18) cm(-2). Excitation temperatures of less than or equal to 50 K for levels J less than or equal to 1 and of similar or equal to 470 K for levels 2 less than or equal to J less than or equal to 4 of H-2 are derived. We conclude that moderate UV pumping influences the population even of the lowest rotational states in this LMC gas.</p
