The Ms values for a d3 configuration refer to the possible values of the spin quantum number (ms) for the three electrons in the d orbitals. Each electron in a d orbital can have either spin up (ms = +1/2) or spin down (ms = -1/2). Therefore, the possible Ms values for a d3 configuration are:
Ms = +3/2: All three electrons have spin up.
Ms = +1/2: Two electrons have spin up, one has spin down.
Ms = -1/2: One electron has spin up, two have spin down.
Ms = -3/2: All three electrons have spin down.
