No. H2 does not have a permanent dipole moment.
H2S is considered a polar molecule. Its construction allows it to have dipoles and dipole moments, which makes it polar.
The molecular dipole moment is a measure of the separation of positive and negative charges within a molecule. It is a vector quantity that indicates the overall polarity of a molecule. It is determined by the individual dipole moments of the bonds within the molecule and their spatial arrangement.
Yes
When molecules have permanent dipole moments
Typically one where bond dipoles do not cancel due to the molecular symmetry. The lone pairs also give rise to a small dipole moment and these may cancel out small bond dipoles it depends on the relative directions of the dipole moments.
because of molecular dipole moments
H2S is considered a polar molecule. Its construction allows it to have dipoles and dipole moments, which makes it polar.
A dipole moment is a mathematical product of the magnitude of a charge and the distance of the separation between charges. There are also many other types of dipole moments, such as transition, molecular, bond and electron.
Ion-dipole, Dipole-dipole, and Dipole-induced dipole.
H2 does not have dipole moment so there is no allowed transition in infrared between vibrational levels.

When molecules have permanent dipole moments
H-H or H2 is molecular hydrogen.
Nonpolar compounds do not have dipole moments. Dipole moments are polar forces. If the compound is nonpolar then there is no polarity within that molecule.
Typically one where bond dipoles do not cancel due to the molecular symmetry. The lone pairs also give rise to a small dipole moment and these may cancel out small bond dipoles it depends on the relative directions of the dipole moments.
