Out of `CS_(2)` and `OCS` which have higher dipole moment and why?

Explanation

Both OCS and `CS_(2)` are linear molecules having, Lewis structure as :

Inb `CS_(2)`, the dipole moment is 0 because the bond moments cancel out. But in OCS, bond moment of `C=O` is not equal to that of `C=S`. Hence, it has a net dipole moment. Thus, dipole moment of OCS is higher.
