The one dimensionality of H2 in the nanotube is well maintained in a large density range, this system being closer to an ideal 1D fluid than liquid 4He in the same setup. H2 shares with 4He the existence of a stable liquid phase and a quasicontinuous liquid-solid transition at very high linear densities.$1 ^{1}B^{+}_{u} \leftarrow 1 ^{1}A^{-}_{g}$ %K Molecular hydrogen %K Carbon nanotubes %~
