As a non zero dipolar momentum implies some asymmetry in the distribution of the electrical charges, it is specially important in non
symmetric molecules.
However, with the latest advancements, cryo - EM can now tackle smaller and less
symmetric molecules.
Symmetric molecules are easier for the computer to align, and large particles produce greater signal intensity.
: it's because it has a dipole moment as it is NOT
a symmetric molecule, like O2 or N2, so it has bending modes that can be excited by infrared radiation); more water vapor = more greenhouse warming, again * all other things being equal *.

molecule.
Both the hydrogen and oxygen
